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).

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).
