Two large parallel metal plates carry charges + Q and - Q respectively. A test charge q 0 placed between them experiences a force F . If the separation between the plates is doubled, then the force on the test charge will be

TestHub · Accepted Answer

Initially, the force on charge q 0 is F = q 0 E The electric field is, E = Q ε 0 A If the separation between the plates is doubled E will remain same as its independent of distance. ∴ F = s a m e
