Question

calculate the force of attraction between 2 bodies each mass 1kg when their centre are 10cm apart given G=6.67into 10 ^-11Nm2by kg2​

Answer 1

Given,

m1 = 1kg

m2= 2kg

r = 10cm= 10×10^-2

FORCE OF ATTRACTION =( G×m1×m2 ) ÷ r^2

= 6.67×10^-11 ×1×1÷10×10^-2×10×10^-2

=6.67×10^-11÷10^-2

= 6.67×10^-9
