Q.

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» C. centre of gravity and centre of equilibrium fall within the feet
Explanation: When the buckets containing equal amount of water are held in both hands, weight is spaced out more evenly than it would be if one had to carry a single bucket. For balancing the weight, the centre of gravity and the centre of equilibrium should fall, in the present case, within the feet.
