Question

15. Two unequal masses m and 2m are connected by a string passing over a
smooth pulley. Find the acceleration and tension in the string.
2m​

Answer 1

Answer:

T - mg = ma -(1)

2mg - T = 2ma -(2)

Explanation:

from equation (1) and (2) we get, a = g/3

Put the value of 'a' in equation (1)

T - mg = mg/3

T = mg/3 + mg

T = 4 mg/3
