It is easier to carry two buckets of water in one hand each, than to carry only one in one hand because
A. Weights of buckets are balanced
B. Centre of gravity falls within the body
C. Centre of gravity and centre of equilibrium fall within the feet
D. Resultant weight of buckets is zero
Answer: Option C
Solution(By Examveda Team)
It is easier to carry two buckets of water in one hand each, than to carry only one in one hand because the centre of gravity and centre of equillibrium fall within the feet. The weight is spaced out more evenly on both the sides of the body than it would be if you had to carry in a single bucket.Which of the following terms is not used in the field of physics?
