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
