Which of the following is a non-contact force ?

Given below are two statements, one is labelled as Assertion (A) and other is labelled as Reason (R). Assertion (A): In simple harmonic motion, the potential energy of the particle is maximum at the…

The linear momentum of a particle is conserved if:

We apply a force of 200 Newtons on a wooden Box and push it on the floor at constant velocity. The marginal friction force will be:
