Question

1. Calculate the force of gravitation between two bodies each of mass 70 kg and placed 14
apart. Take G = 6.67 * 10-11 Nm"/kg?​

Answer 1

Answer:

Explanation:

gravitation between two bodies  can be calculate by using the formula

 g=GMmr^-2

here r=14cm=0.14m, r^2 =0.0196

    m=M=70kg

 

G=6.67 X 10^-11

 

SO, g=[( 6.67*10^-11m^3 kg^-1 s^-2) (4900kg^2) ]/0.0196 m^2

   

       g=1.6675m/s^2
