Two similar spheres having 
and 
charge are kept at a certain distance. 
force acts between the two. If in the middle of two spheres, another similar sphere having 
charge is kept, then it experience a force in magnitude and direction as
A
Zero having no direction
B
towards 
charge
C
towards 
charge
D
towards 
charge
Text Solution
Verified by ExpertsThe correct answer is:
C
Initially, force between A and C
When a similar sphere B having charge +Q is kept at the mid point of line joining A and C, then Net force on B is 
.
(Direction is shown in figure)
