Question: The kinetic energy acquired by a mass m in travelling a certain distance d starting from rest under the action of a constant force is directly proportional to [CBSE PMT 1994]
Options:
A) $ \sqrt{m} $
B) Independent of m
C) $ 1/\sqrt{m} $
D) m
Show Answer
Answer:
Correct Answer: B
Solution:
Kinetic energy acquired by the body = Force applied on it × Distance covered by the body K.E. = F × d If F and d both are same then K.E. acquired by the body will be same
