Answer and Explanation
- JEE Mains 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.
- JEE Mains 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.
- JEE Mains 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.
- JEE Mains 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.
