Question

If m1 is the mass of the earth (6x10^24kg), m2 is the mass of the moon (7 x10^22kg) and r is the distance between moon and the earth (3 x10^5km), then force exerted by the earth on moon is​

Answer 1

F= (3.84×10 8 ) 2

6.7×10 −11 ×6×10 24×7.4×10 22

= (3.84) 2 ×10 16

297.48×10 −11+24+22

=20.17×10
