Question

The mass of a body is 35kg.Taking the pull of gravity on mass 1 kg equal to 10 N. Express the weight of the body in (i) kgf (ii)newton. ​

Answer 1

Explanation:

GivEn :

Mass = 35 kg

1kg = 10 N

To find :

We need to express the weight of the body in kgf.

SoluTion :

As we know the formula of force required,

➝ F = m × a

➝ F = 35 × 10 ⠀[As it is given that a = g]

➝ F = 350 N

Also, we know that,

1 kgf = 9.80665 N

So,

➝ F = 350 × 9.80665

➝ F = 3432.32 kgf or 3500 kgf [approx.]

\therefore∴ Weight of the body is 3432.32 kgf.
