Question

5. A body of mass 40 gm is moving with a con-
stant velocity of 2 cm/sec on a horizontal fric-
tionless table. The force on the table is :
(a) 39200 dynes (b) 160 dynes
(c) 80 dynes
(d) zero dynes​

Answer 1

Answer:The answer is d zero dynes

Explanation: As you know force is the product if mass and acceleration

As velocity is constant here, the acceleration will be zero. So force will also be zero
