Two point charges 
and 
are at 16 cm away from each other. Where should another charge q be placed between them so that the system remains in equilibrium
A
24 cm from 
B
12 cm from 
C
24 cm from 
D
12 cm from 
Text Solution
Verified by ExpertsThe correct answer is:
B
Suppose q is placed at a distance x from +9e, then for equilibrium net force on it must be zero i.e. |F 1 | = |F 2 |
Which gives
