Not sure but i will say D
The Mass of the barter and the ball is 3.1kg
Data Given;
- F = 1.1*10^-9N
- r = 0.76m
- G = 6.67*10^-11 m^3 kg^-1 s^-1
Assuming the barter and the ball have equal mass, we can apply gravitational force formula.
<h3>Gravitational Force</h3>

This is product of the mass of the two bodies and divided by the square of their distance apart.
Substituting the values into the formula

From the calculations above, the mass of the barter and the ball is 3.1kg
