Question

#For Physics Newton


an object of mass 250 gram is taken at a height of 3200 km above the Earth surface. find increase in the gravitational potential energy if the object is further raised through a height of 90cm.​

Answer 1

Answer:

is ans= 220,578.4

Explanation:

the formula is mgh for potential energy.

3200 is in km

therefore, 0.032cm

h= 90+0.032

= 90.032

E(potential)= mgh

= 90.032×9.8×250

=220.578.4 J

Hope its useful.
