In outer space, a bowling ball and a Ping$-$Pong ball attract each other due to gravitational forces.$$ How do the magnitudes of these attractive forces compare?

$1)$ the bowling ball exerts a greater force on the Ping$-$Pong ball

$2)$ the Ping$-$Pong ball exerts a greater force on the bowling ball

$3)$ the forces are equal

$4)$ the forces are zero because they cancel out

$5)$there are actually no forces at all
