Physics Systems of Particles and Rotational Motion MHT CET

When a steady torque or couple acts on a body, the body

(A)continues in a state of rest or of steady motion by Newton's first law
(B)gets linear acceleration by Newton's second law
(C)continues to rotate at a steady rate
(D)gets an angular accelerationCorrect

Answer: (D)

Solution

A steady torque produces a constant angular acceleration ; a couple has no net force so
