Question

if weight of a body is 50N.what is its mass(g=9.8m/s2

Answer 1

We have,
mg = 50N
g= 9.8m/s^2

A/Q,

If mg =50N
=m x g
= m x 9.8
so, m = mg/g
= 50/9.8
=500/98
=5.10 kg (approx)

Answer 2

Given,

A body of weight (W) = 50N

gravitational acceleration (g) = 9.8 $m/s^{2}$

To find,

Mass of the body (m)

Solution,

The relation between mass and weight of a body is given by,

W= mg,

50 = m × 9.8

m = $\frac{50}{9.8}$,

m = 5.1 Kg

Therefore, the mass of the body is 5.1 kgs.
