  A force of 30 N produces an acceleration of m/s2 in a body of mass m. Find the mass of the body. Also find the acceleration if force is doubled in magnitude along the same direction.

Answer:

                  Force, F = 30 N, Acceleration a = 2 m/s2 Mass of a body If F  is doubled,  a is doubled as   (m is constant) So             a =4 m/s2                           (1)
