PhysicsEasysingle choice

If a body of mass $m$ is moving on a rough horizontal surface of coefficient of kinetic friction $μ$ , the net electromagnetic force exerted by the surface on the body is

Options:

Answer:

Solution:

As, normal force and friction force are the two electromagnetic forces acting on the body

The net electromagnetic force $= \sqrt{N^{2} + f^{2}}$

But $N = m g, f = μ m g$

Force = $m g \sqrt{1 + μ^{2}}$
