Question

two ball of masses 40 kg and 80kg are placed at a distance of 8m from each other .Find the gravitational force acting on the two bodies

Answer 1

hey mate...........☺


answer is.. = Gravitational Force is given by F= GMm/R^2

F=6.67x10^-11 x 40 x 80 / (15x15)

= 6.67x10^-11 x 14.22 N

= 9x10^-10 N

hope it's help uhh

Answer 2

Hello Mate.

Thanks for asking this question.

Your answer is =>

Here , you have given the masse of two balls as =>

=> mass of 1st ball = 40 Kg = $M_1$

=> mass of 2nd ball = 80Kg=$M_2$

also , distance between them is = 8 m.

to find the gravitational force between them , we use a relation as =>

$=>\boxed{ F \:=\: \frac{G \times M_1 M_2}{R^{2}}}$

where ,

G = gravitational constant = $6.67\times 10^{-11} \frac {N{m^{2}{Kg^{2}}$

now , putting the given values , we get ,

$=>F\:=\:\frac{6.67 \times 10^{-11} \times 40 \times 80}{8^{2}}$

$=>{F\:=\: 333.5 \times 10^{-11} \:N }$

$=>\boxed{F\:=\: 3.335 \times 10^{-13} \:N}$

Gravitational force between them is $333.5 \times 10^{-11} \:N$
