Class XI A particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle. The motion takes place in a plane. It follows that its acceleration is constant its motion is circular its velocity is constant its motion is linear One o (1o) is equal to? 0.1745 rad 0.01745 rad 0.001745 rad 7.1745 rad Kicked or thrown balls, jumping animals, object thrown from a window, a missile shot from a gun, a bomb released from a bomber plane, etc are all example of? Mechanical energy Projectiles Velocity Machine A body of mass 500 gram is rotating in a vertical circle of radius 1 m. What is the difference in its kinetic energies at the top and the bottom of the circle? 4.9 J 19.8 J 2.8 J 9.8 J The range of the projectile depends on the square of the initial velocity and? cosine of twice the project angle θ sine of twice the projection angle θ sine of thrice the projection angle θ cot of twice the projection angle θ Do you really want to submit this quiz?
