Question

Two bodies of masses 15gm and 25gm are
connected by means of a string of length 40cm
and mass 10gm. The string is made to pass over
a smooth massless pulley. Initially the two
bodies are kept at the same level and released
By the time the heavier mass descends by 10cm,
the acceleration of the system,
3
1) Remains constant
O
2) Decreases
3) Increases by a factor 1.5
4) Increases by a factor 3
​

Answer 1

Answer 2

Answer:

1)Remain constant

Explanation:

concept - let the 15gm box mass ,M1 and 25gm box mass , M2

tension in the string of the pulley is T

acceleration

explanation:

M2g -T =M2a ----1

T- M1g =M1a -----2

a=(M2-M1)g/M1+M2

a=g(25-15)/25+15

a=g*10/40

a=g

a=10m/s-2
