12 identical charges q are placed at the corners of a regular 12-sided polygon.
a) What is the net force on a test load Q at its center.
b) Suppose one of 12q is removed, what will be the total force on Q?
Four identical point charges of magnitude q = 3.2 nC are placed
at the corners of a rhombus of edge length l = 22 cm and obtuse
angle θ. We intentionally leave θ undefined. Find the net electric
force on each of the four charges. Your answer will depend on the
angleθ. For convenience, orient your rhombus so that the charges
are placed at (±x, 0) and (0, ±y).
Find the perimeter of a regular 36 sided regular polygon
inscribed in a circle with a radius of 14 units. Then find the size
of one of the inscribed angles.
Four charges of magnitude +q are placed at the corners of a
square whose sides have a length d. What is the magnitude of the
total force exerted by the four charges on a charge Q located a
distance b along a line perpendicular to the plane of the square
and equidistant from the four charges? Ans: bqQ/πε 0 (b2 + d2 / 2)
how to get this answer?
Two identical point charges (q = +3.00 x 10-6 C) are fixed at
opposite corners of a square whose sides have a length of 0.580 m.
A test charge (q0 = -3.00 x 10-8 C), with a mass of 7.50 x 10-8 kg,
is released from rest at one of the corners of the square.
Determine the speed of the test charge when it reaches the center
of the square.
Two identical point charges (q = +5.80 x 10-6 C) are fixed at
opposite corners of a square whose sides have a length of 0.320 m.
A test charge (q0 = -7.90 x 10-8 C), with a mass of 6.20 x 10-8 kg,
is released from rest at one of the corners of the square.
Determine the speed of the test charge when it reaches the center
of the square.
Two charges, + q and - q, occupy two corners of an equilateral
triangle, as shown in FIGURE 19-51. (a) If q = 1.8 mC and r = 0.50
m, find the magnitude and direction of the electric field at point
A, the other vertex of the triangle. Let the direction angle be
measured counterclockwise from the positive x axis. (b) What is the
total electric flux through the surface indicated in the figure?
(c) Explain why Gauss’s law cannot...
Four identical bowling balls are placed on the corners of a
square drawn on the ground whose sides are each .2 meters long. If
the mass of each ball is 4kg, a)What is the magnitude of the net
gravitational force acting on one of the balls due to all others,
b)what is the magnitude and direction of the resulting acceleration
of that ball? Please give full steps so I can follow along. TIA
Three point charges are placed at the corners of a right-angle
triangle, as shown in the figure. The masses, charges and
coordinates of the three objects are given as follows: Mass (g):
Charge (μC): Coordinate (mm): ?1 = 2.30 ?1 = −1.25 ?1 = (0; 6.00)
?2 = 0.15 ?2 = +0.55 ?2 = (0; 0) ?3 = 1.50 ?3 = −2.05 ?3 = (4.00;
0) (a) Determine the coordinate of the centre of mass of the
system. (b) Calculate...
Four charges are placed on the corners of a rectangle with
length d = 0.00341 mm and breadth s = 0.00119 mm, as shown in the
figure. The charges are given in terms of the elementary charge, e
= +1.602×10‒19 C, as follows: q1 = q2 = +2000e and q3 = q4 =
‒3000e.
(a) Calculate the electric potential at point A, the middle of
the rectangle, and at point B, the middle of the right-hand side of
the rectangle....
Q 4 One can think of a circle as an N-sided polygon where N is a
very very large number. This is because as the number of sides of a
polygon increases the shape of the polygon starts resembling that
of a circle. In the light of this fact explain why the diffraction
pattern produced by the aperture DOTS is made of alternating bright
and dark circular bands.
Hint: First determine the diffraction pattern produced by an
N-sided polygon. Then...
