Question

Martha's car is parked in a garage. It is at rest, and the forces acting upon the car include

Answer 1

A magnetic force.
B electrical force
C gravitational force.

Answer 2

Gravitational Force:
The car is at rest, so a force acting upon it is gravity, because gravity is always acting
on objects on the Earth. Also, the force of the ground pushing up on the car is there
balancing out the force from gravity to keep the car at rest.
Hope this helps :D
