A large SUV is placed on top of Piston B of the hydraulic lift shown in the image. The car has a mass of $2160$ $kg$.

If Piston B has a radius of $7$ $m$ and Piston A has a radius of $0.5$ $m$, what force must be applied to Piston A such that the SUV remains in equilibrium? Both pistons are cylindrical.

A

$21,190$ $N$

B

$1,513$ $N$

C

$108$ $N$

D

$4.15\cdot { 10 }^{ 6 }$ $N$
