Explanation / Answer

a) the correct option is second option . The load applied by farmer is in the upward direction whereas the weight of bucket and water act in the downward direction.

b)upward force applied by farmer=49.5 N

mass of bucket = 1.5 kg

Weight of bucket=1.5*9.8=14.7 N

Weight of water = 49.5-14.7=34.8 N

mass of water = 34.8/9.8=3.55 kg

c)density of water= 1gm/cc = 0.001kg/cc

mass of water = 3.55 kg

volume of water = 3.55/0.001=3550 cc
