JEE MainPhysicsLaws of MotionMCQ+4 / −1
A block of mass 5 kg is (i) pushed in case (A) and (ii) pulled in case (B), by a force F = 20 N, making an angle of 30o with the horizontal, as shown in the figures. The coefficient of friction between the block and floor is μ\muμ = 0.2. The difference between the accelerations of the blocks, in case (B) and case (A) will be : (g = 10 ms–2) JEE Main 2019 (Online) 12th April Evening Slot Physics - Laws of Motion Question 104 English
