Question

If initially flux through hemisphere is zero. Now q1 and q2 placed according to figure. Due to which charge flux through hemisphere will change :- (A) Only q 1 (B) Only q 2 (C) Both (D) None

Field lines of q 1 passes through surface of hemisphere one time. Field lines of q 2 passes through surface of hemisphere two time so net flux due to q 2 is zero. Net flux due to q 1 is non zero.

Q. If initially flux through hemisphere is zero. Now $q_{1}$ and $q_{2}$ placed according to figure. Due to which charge flux through hemisphere will change :-

Only $q_{1}$

Only $q_{2}$

Both

None

Field lines of $q_{1}$ passes through surface of hemisphere one time.
Field lines of $q_{2}$ passes through surface of hemisphere two time so net flux due to $q_{2}$ is zero.
Net flux due to $q_{1}$ is non zero.
