Question

The following figure shows forces acting on the blocks A, B, C, D. Which of the following option is incorrect?

• A. Net force acting on block A is 4 N
• B. Net force acting on block D is 6 N
• C. Net force acting on block C is 16 N
• D. Net force acting on block B is 2 N

Answer 1

The correct option is C Net force acting on block C is 16 N

Forces on each Block are in the opposite direction.
Net force can be found by subtraction of forces.

Net force on block A = 6 N - 2 N = 4 N

Net force on block B = 4 N - 2 N = 2 N

Net force on block C = 8 N - 8 N = 0 N

Net force on block D= 8 N - 2 N = 6 N
So Option C is incorrect
