The flat base of a hemisphere of radius a with no charge inside it lies in a horizontal plane. A uniform electric field E is applied at an angle 4 with the vertical direction. The electric flux through the curved surface of the hemisphere is

Options

  1. Aa^2 E
  2. Ba^2 E 2
  3. Ca^2 E 2 2
  4. D( +2 ^2 E . (2 2 ^2 )

Correct answer

B. a^2 E 2

Step-by-step solution

We know that, = E d S=E d S 45^ In case of hemisphere _ curved = _ circular Therefore, _ curved =E a^2 1 2 = E a^2 2
