Q8 of 94 Page 440

Two protons are kept at a separation of 10nm.Let Fn and Fe be the nuclear force and electromagnetic force between them.

The correct answer will be (b).This is because electromagnetic force is .Whereas nuclear force is


Option (a) is not correct as nuclear forces and electromagnetic forces can’t be equal because electromagnetic force is much stronger than nuclear force.


Option (c) is not correct as nuclear force is not stronger than electromagnetic force.


Option (d) is also not correct as they differ by a large margin.
