A spring balance is used to find the weight of a body x on the surface of the moon. The mass of the body x is 2 kg and its weight is recorded as 3.4N . The weight of another bodyY recorded by the same balance is found to be 7.65N.Calculate the mass of the body Y

Here Use formula w = mg
then for X,
m = 2Kg and W = 3.4 N
so g = W/m = 3.4/2 = 1.7 m/s2
and for Y,
W = 7.65 N and m = ?
m = W/g = 7.65/1.7 = 4.5 Kg
so 4.5 Kg is the correct answer.

The mass of the body Y is 4.5 kg
Explanation:
Body X:
Mass (m) = 2 kg
Weight (W) = 3.4 N
Weight of the Moon is given by the formula:
W = m × gm → Equation (1)
⇒ gm = W/m
On substituting the values, we get,
gm = 3.4/2
∴ gm = 1.7 m/s²
Body Y:
Weight (W) = 7.65 N
On substituting the above values in equation (1), we get,
Mass of Y = W/gm
Mass of Y = 7.65/1.7
∴ Mass of Y = 4.5 kg
