Question

The acceleration produced in a body by a force of given magnitude depends on — (a) size of the body (b) shape of the body (c) mass of the body (d) None of these

March 12, 2024

Answer

(c) mass of the body

Reason — As we know,

Force (f) = mass (m) x acceleration (a)

Hence, the acceleration produced in a body by a force of a given magnitude depends on the mass of the body.
