Option A is correct
Weight = 32.2 N
Given that,
acceleration due to gravity on the surface of Mercury = 3.71 m/s².
Mass of object = 8.69 kg
To find,
weight of object on Mercury
Formula to calculate weight
W = 8.69 x 3.71
W = 32.24 N
W ≈ 32.2 N
So, the weight of object of mass 8.69kg on Mercury = 32.2 N
The correct choice is 32.2 N
According to the definition of weight
W = m * g
Where W is the weeight, m i the mass and g is value of gravity
So putting the values
W = 8.69 kg * 3.71 m/s²
W = 32.2 N
