Question

A man have weight 600N on surface of Earth. Find the weight of that mean on the surface of planet having man 7×10power23 and radius 600000m . Also calculate weight of that man at height 88480. above from the surface of the planet​

Answer 1

Explanation:

Weight on earth = 600N

Let g= 10m/s

2

on earth

Mass on earth =

10

600

=60 kg

Now, since mass is a constant quantity so, it will remain 60 kg on the moon also.

Now, weight on moon = mg

′

m= mass =60 kg

g

′

= acc. due to gravity on moon =

th

the value on earth

So, Weight on moon =

th

of the weight on earth

⇒ Weight on the moon =600×
