Answer 1

Answer:

1.0421875 × 10^-9

Explanation:

Gravitational Force = 6.67*(10^-11)*20*50/8^2

= 1.0421875 × 10^-9

Answer 2

Answer:

1.0421875 x 10^-9{negligible}

Explanation:

M= 20 kg

m= 50 kg

G =6.67 x 10^ -11

r= 8 m

g=G x M x m/ r ^2

= G 20 x 50/8^2

=G 1000/64

=6.67 x 10^ -11 x 1000/64

=0.0000000010421875

=1.0421875 x 10^-9
