TRANSLATORY MOTION

Assertion : Like forces equal in magnitude simultaneously acts on a body leads translatory or rotatory motion . Reason : Act in the same direction of action of force leads translatory , acting tangent to the body leads rotatory .

An electric dipole of dipole moment p, is held perpendicular to an electric field. If the dipole is released does it have (a) only rotational motion (b) only translatory motion (c) both translatory and rotatory motion explain?

Statements : (a) In translatory motion each point of the body experiences the same displacement as any other point as time goes on, so that the motion of any particle epresents the motion of the whole body. (b) In rotatory motion, all the particles in the rigid body moves in concentric circles about the axis of rotation.

A bar of mass 'm' length 'l' is in pure translatory motion with its centre velocity 'v' It collides with another identical bar which is in rest and sticks to it. Assume that after the collision it becomes one system, then the angular velocity of the system after the collision is. .
