MHT CET 2026 Physics question
Two point charges +e and +4e are kept at a distance 'd' units apart. Third point charge +q is placed between the two charges at a distance 'x' units from charge +e so as to be in equilibrium. The value of 'x' is
Answer: (A)
Solution
For +q to be in equilibrium the forces from the two fixed charges must cancel: . This gives , so (positive root, since the point lies between the charges)
