Question

the weight of body of mass 3kg at a height of 12.8×10^6 m from the surface of the earth is ?

Answer 1

Actually weight(w) only depends upon mass(m) and acceleration due to gravity(g)

W=mg

m=3kg
g=9. 8m/s

w= 3×9.8= 29. 4

weight of body is 29. 4 N, If i am not wrong

Answer 2

Answer: The weight of body =29.4 N

Step-by-step explanation:

The weight (in Newton)of a body is given by :-

$\text{Weight= Mass}\times\text{Acceleration due to gravity}$

Given : Mass of the body = 3 kg

Acceleration due to gravity = $9.8\ m/s^2$

Then, the weight of body will be :-

$\text{Weight}=3\times9.8=29.4\ \text{N}$

Hence, the weight of body =29.4 N
