Question

A body of mass 1kg is attracted by the earth with a force which is equal to

Answer 1

acceleration due to gravity g = 9.8 m/s
mass. m = 1kg
force. = m ×a
= 9.8 × 1
=9.8N

Answer 2

"A body of mass 1kg is attracted by the earth with a force is equal to 9.8 N .

We know that,

"Acceleration due to gravity" g $= 9.8 \frac { m }{ s }$

Given mass 'm' = 1kg

The force with which earth pulls = mass of the body × acceleration due to earth's gravity

That is, F = ma

$=\quad 1kg\times 9.8\frac { m }{ { s }^{ 2 } } = 9.8\quad kg\frac { m }{ { s }^{ 2 } }$

= 9.8N

Hence, the force is equal to 9.8 N"
