Assume a $1000\text{ kg}$ spacecraft is exactly at the midpoint (P) between two planets. Planet A is to the left of the spacecraft and has a gravitational field of $2\text{ N/kg}$ at point P. Planet B is to the right of the spacecraft and has a gravitational field of $0.5\text{ N/kg}$ at point P. What is the magnitude of net force on the spacecraft due to the gravity of the two planets?

A

$0\text{ N}$, since the spacecraft is an equal distance from each planet.

B

$2.5\text{ N}$

C

$1.5\text{ N}$

D

$1500\text{ N}$
