Asked by huhhf3;q

A student shows the following work to calculate the gravitational force between two identical objects with masses of 740 g that are 5 m apart.
Fg =-6.674 × 10-11 (240)(740) = - 1.462 × 10-6 N
Which statement indicates why the work is incorrect?
(1 point)
The student did not use the correct signs.
The student did not convert the distance to kilometers.
The student did not multiply or divide values correctly.
The student did not convert the masses to kilograms.

The student did not convert the masses to kilograms.

Explanation: 740 g = 0.740 kg, so
F = G(0.740)(0.740)/5^2 = 6.674×10^-11·0.5476/25 ≈ 1.46×10^-12 N (attractive).
Not converting each mass from g to kg leaves a factor 10^3×10^3 = 10^6 too large, giving ~1.46×10^-6 N.
