The net applied force on a body in uniform circular motion should always be
Constant in magnitude and parallel to direction of motion
Constant in magnitude and perpendicular to direction of motion
Gravitational in nature
Zero
If a force of constant magnitude acts in direction perpendicular to the motion of a particle, then its
If the body is moving in a circle of radius $ r$ with a constant speed $v$, its angular velocity is
For a particle in uniform circular motion, the acceleration $\vec a$ at a point $P(R,\theta)$ on the circle of radius $R$ is (Here $\theta$ is measured from the $x-$ axis)
A particle is in uniform circular motion, then its velocity is perpendicular to
A particle moves with constant angular velocity in circular path of certain radius and is acted upon by a certain centripetal force $F$. if the angular velocity is kept same but the radius of the path is halved, the new force will be
