Consider the following statements about the blocks shown in the diagram that are being pushed by a constant force on a frictionless table
(a) All blocks move with the same acceleration
(b) The net force on each block is the same Which of these statements are/is correct

Options

A. A only
B. B only
C. Both A and B
D. Neither A nor B

Answer

A

Explanation

Acceleration of system ` (a) = (F)/(3+2+1) = (F)/(6) m//s^(2)`
Force on 3 kg `= 3 xx a = 3a`
Force on 2 kg ` = 2 xx a = 2a`
Force on 1kg ` = 1 xx a = 1a`
