A particle dropped from the top of a tower uniformly falls on ground at a distance which is equal to the height of tower. Which among the given paths will be traversed by the particle
A particle enters uniform constant magnetic field region with its initial velocity parallel to the field direction. Which of the following statements about its velocity is correct? (neglect the effects of other fields)
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 takes place in a plane. It follows that
A particle is moving in a uniform circular motion with constant speed v along a circle of radius r. The acceleration-of the particle is
A particle is moving in translatory motion. If momentum of the particle decreases by 10%, kinetic energy will decrease by
