A body of mass 40 gram is moving with constant velocity of 2 centimetr...
Solution:
Given,
Mass of the body, m = 40 g = 0.04 kg
Velocity of the body, v = 2 cm/s = 0.02 m/s
As the body is moving with a constant velocity on a frictionless table, the net force acting on the body is zero.
Therefore, the force on the body in dynes is:
F = m × a
where a is the acceleration of the body.
As the body is moving with a constant velocity, its acceleration is zero.
Hence, F = m × a = 0
Therefore, the force on the body in dynes is 0 (option a).
