Question

Two smooth balls, A of mass 4 kg and radius 1 cm and B of mass 3 kg and radius 4 cm are placed at a smooth corner. A horizontal force F is acting on A. The minimum value of F to lift the ball B from the ground is


A) 20 N

B) 32.5 N

C) 40 N

D) 45 N

Answer 1

Answer:

the answer is D

Explanation:

the answer is 45

Answer 2

The correct answer is option (D) 45 N.

Explanation:

• Two smooth balls, A of mass 4 kg and radius 1 cm and B of mass 3 kg and radius 4 cm are placed at a smooth corner.
• A horizontal force F is acting on A. The minimum value of F to lift the ball B from the ground is 45 N.
• Mass is measured in kilograms in the SI system. Newton's Second Law is a relation between the net force (F) acting on a mass m and its acceleration a.
