Question

Mukul is trying to pull a load on an inclined plane. Which of the following forces should be overcome?
A: Gravitational force
B: Electrostatic force
C: Frictional force
D: Magnetic force

• A. A and B
• B. A and D
• C. A and C
• D. Only A

Answer 1

The correct option is C A and C

Gravitational force due to earth always acts downwards. If the body is being pulled up an inclined plane, a part of force of gravity acts in the opposite direction, making it one of the forces to overcome.

Frictional force always tries to oppose motion between surfaces in contact.

Therefore, Mukul needs to overcome both gravitational and frictional forces to pull the load up the incline.
