What is the minimum downward force magnitude on the box, F, that will keep it from slipping?
What is the minimum downward force magnitude on the box, F, that will keep it from slipping? The coefficients of kinetic and static friction between the box and the floor are 0.200 and 0.400, respectively.
To understand the concept of tension and the relationship
between tension and force.This problem introduces the concept of tension. The example is a
rope, oriented vertically, that is being pulled from both ends.
(Figure 1) LetFu and Fd (with u for up and d for down)
represent the magnitude of the forces acting on the top and bottom
of the rope, respectively. Assume that the rope is massless, so
that its weight is negligible compared with the tension. (This is...
What is the magnitude and direction of an electric field if it
exerts a downward force of 10-6N on a charge of -5μC?
Could you please explain how to do this question? Thank you
A downward force of 3.7N is exerted on a -5.4μC charge. (a) What
is the magnitude of the electric field at this point? (b) What is
the direction of the electric field at this point?
What is the magnitude of the force acting downward (in lbs) on the average adult human head due to atmospheric pressure? Idealize a head as a sphere of circumference 55 cm. Note: 1 N is equal to 0.224 lb.
A force of constant magnitude pushes a box up a vertical
surface, as shown in the figure.
The box moves at a constant speed. If the mass of the box is 4.0
kg, and it is pushed 2.2 m vertically upward, the coefficient of
friction is 0.35, and the angle θ is 37°. What is the work
done by the force, F? Use g = 10 m/s2.
Coulomb's law for the magnitude of the force F between two
particles with charges Q and Q′ separated by a distance d is
|F|=K|QQ′|d2, where K=14πϵ0, and ϵ0=8.854×10−12C2/(N⋅m2) is the
permittivity of free space. Consider two point charges located on
the x axis: one charge, q1 = -18.0 nC , is located at x1 = -1.680 m
; the second charge, q2 = 39.5 nC , is at the origin (x = 0).

You are pushing a box (m = 4 kg) horizontally with a constant
force F = 30 N. After pushing it for a distance d = 5 m, the box
reaches a hill inclined at θ = 25°. You stop pushing the box as
soon as it reaches the hill. The coefficient of kinetic friction
between the box and the road is µk = 0.4 and the hill is
frictionless. How far up the hill is the box going to...
What is the difference in finding magnitude of a force on a
charge and finding the net electric force acting on a charge?
If given three charges set at a certain places set on a
triangle, how would you find the magnitude of a force on one of the
charges? Please create a simple example and show each step clearly
and explanation for what to do in each step esecially on how to
find, set up, and use the components...
