Forces On Bodies Contact & Non-Contact Forces

Answer and Explanation

• NEET 2018:

The answer is (A) circular.

A particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle. The motion of the particle is circular.

• NEET 2017:

The answer is (A) mv2/r.

The centripetal force acting on a particle of mass m moving in a circular path of radius r with a constant speed v is given by F = mv2/r.

• NEET 2016:

The answer is (A) mvr.

The angular momentum of a particle of mass m moving with constant speed v in a circular path of radius r is given by L = mvr.

• NEET 2015:

The answer is (A) mv2/r.

The centripetal force acting on a particle of mass m moving in a circular path of radius r with a constant speed v is given by F = mv2/r.
