Question

You place a 0.13 kg can of soup and a 0.33 kg jar of pickles on the kitchen counter, separated by a distance of 0.42 m

What is the magnitude of the force of gravity that the can of soup exerts on the jar of pickles.

Express your answer to two significant figures and include the appropriate units.

Answer 1

Gravitational constant = G = 6.67 x 10^-11 N.m²/kg²

Mass of the can of soup = m₁ = 0.13 kg

Mass of the jar of pickles = m₂ = 0.33 kg

Distance between them = D = 0.42 m

Force of gravity that the can of soup exerts on the jar of pickles = F

$F = \frac{Gm_{1}m_{2}}{D^{2}}$

$F = \frac{(6.67\ast 10^{-11})(0.13)(0.33)}{(0.42)^{2}}$

F = 1.6 x 10^-11 N

Magnitude of force of gravity that the can of soup exerts on the jar of pickles = 1.6 x 10^-11 N
