Question

3. M+m M + m Four blocks 1 kg, 2 kg, 3 kg, 4 kg are placed in contact on the frictionless surface, force of 10 N acts horizontally on 4 kg block. The acceleration produced in the system is (1) 2 m/s2 (2) 3 m/s2 (3) 1 m/s2 (4) 4 m/s2 An engine pulls a train with 80 compartments with 4.​

Answer 1

Explanation:

No of blocks placed in contact on the frictionless force=4

force=10N

masses=1kg+2kg+3kg+4kg=10kg

we need to find acceleration which will be calculated by

Acceleration=force/mass = 10/10=1 therefore the acceleration produced in the system=1m/s²
