Question

A body is acted upon by two equal and opposite forces along different lines of action of force. The body will have:

Options

• only rotatory motion

• only translatory motion

• both rotatory and translatory motion

• neither rotatory nor translatory motion

Answer 1

Only rotatory motion

Explanation:

Equal and opposite forces acting along different lines form a couple. Their resultant force is zero, so they do not cause translatory motion, but they produce rotation.
