Question

A body is moving with uniform velocity of
50 km/h, the force required to keep the body
in motion in SI unit is ?
(A) zero
(B) 10
(C) 25
(D) 50​

Answer 1

Answer:

a)

as the body is in uniform motion hence no external force is acting on it. therefore no force is required to change the state of its motio

Answer 2

Answer: (A) zero

Explanation:

• It is to be understood that if a body is in uniformmotion then no external force is affecting the motion of the body.
• So, to remain in motion no force is required to be applied on the body.
• So, we can say the first option zero will be the appropriate answer.
• Hence, option (A) is the answer.
