The elevator shown in figure is descending with an acceleration of 2 ms –2 . The mass of the block A = 0.5 kg. The force exerted by the block A on the block B is (take g = 10 m/s 2 )
Text Solution
Verified by ExpertsThe correct answer is:
B
m A g – N A = m A a
N A = m A (g – a)
= 0.5 (10 – 2)
= 4 N
