The drawing shows an edge-on view of two planar surfaces that intersect and are mutually perpendicular. Surface 1 has an area of 1.5 m2, while surface 2 has an area of 3.4 m2. The electric field E in the drawing is uniform and has a magnitude of 190 N/C. It is directed towards the two perpendicular surfaces, making an angle 35o with the bottom surface. Find the electric flux through (a) surface 1 and (b) surface 2.

Solutions

Expert Solution

Remember electric flux is given by:

= E.A

= E*A*cos theta

Where E = electric field = 190 N/C

A = area of surface

theta = angle between electric field and surface in the direction of electric field (Important)

Part A.

For surface 1

A1 = Area of surface 1 = 1.5 m^2

theta1 = 35 deg

So,

1 = E*A1*cos theta1

1 = 190*1.5*cos 35 deg

1 = 233.5 N-m^2/C

Part B.

For surface 2

A2 = Area of surface 2 = 3.4 m^2

theta2 = 90 - 35 = 55 deg (Since surface 1 and surface 2 are perpendicular)

So,

2 = E*A2*cos theta2

2 = 190*3.4*cos 55 deg

2 = 370.5 N-m^2/C

The drawing shows two planes each dropping an empty fuel tank. At the moment of release each plane has the same speed of 194 m/s, and each tank is at the same height of 2.80 km above the ground. Although the speeds are the same, the velocities are different at the instant of release, because one plane is flying at an angle of 15.0° above the horizontal and the other is flying at an angle of 15.0° below the horizontal....
