Question

point charge Q is centered in a spherical surface. Is the electric flux through the sphere anged: [5 marks] If the sphere is replaced by a cube of one-third the volume? (yes/no) ii. If the sphere is replaced by a cube of one-th ii. If the charge is moved off center,b the center, but, remaining inside the sphere? (yes/no) the charge is moved just outside the original sphere? (yes/no) f a second yes/no) iv. If v. I phere? charge is placed near, and outside, the original s f a rectangular area is rotated in a uniform electric field from the position where the rough it,what has been the angle of rotation hrough it to an orientation where only half the Is marks/ .30 n. 45 G0 4TEue or false? . Along an equipotentiat surface, the electri electric fieh, lines

Explanation / Answer

from Gauss law,

flux through closed surafce = Qin / e0

(i) independent of type of surface. so flux will not change

(ii) independent . flux will not change

(iii) still QIn is same so flux will be same.

(iv) charges is moved oustide then flux will become zero.

flux is changed.

(v) Qin is same. No

Ans:
(i)No

(ii)NO

(iii)No

(iv)Yes

(v)NO
