Question

a body having maas 10kg is attracted by the earth with a force what is the value of force ?(g=9.8m/s2​

Answer 1

Answer:

FORCE = MASS × ACCELERATION DUE TO GRAVITY

F = 10 × 9.8

= 98 N

Answer 2

Given:

A body having maas 10kg is attracted by the earth with a force. Value of Gravitational Acceleration is 9.8 m/s².

To find:

Value of the attractive force ?

Calculation:

Gravitational force on the mass be denoted as F;

According to NEWTON'S LAW OF GRAVITATION:

$\boxed{\rm \therefore \: F = \dfrac{GMm}{ {r}^{2} } }$

• M is mass of earth, r is radius of earth, G is Universal Gravitational Constant.

• m is mass of object.

$\rm \implies\: F = m \times \bigg( \dfrac{GM}{ {r}^{2} } \bigg)$

• Now, the term GM/r² actually represents the gravitational acceleration on the body.

• So, GM/r² can be represented as "g".

$\rm \implies\: F = m \times \bigg( g\bigg)$

$\rm \implies\: F = 10 \times 9.8$

$\rm \implies\: F = 98 \: N$

So, the 10 kg mass is pulled with 98 N force towards the earth.
