Two particles having positive charges 
and 
are fixed at equal distance 
from centre of a solid conducting sphere having zero net charge and radius 
as shown. Initially the switch 
is open. After the switch 
is closed, the net charge flowing out of sphere is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
After the sphere is grounded, potential of the conductor becomes zero.
Let the net charge on sphere finally be 
.
∴ The charge flowing out of sphere is
