NDA 2023 Physics question
One block of 2·0 kg mass is placed on top of another block of 3·0 kg mass. The coefficient of static friction between the two blocks is 0·2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as , the maximum value of the frictional force is :
Answer: (C)
Solution
The friction between the blocks acts on the upper block, whose normal reaction is $N = 2
