Two bodies of mass 4   kg and 6   kg are tied to the ends of a massless string. The string passes over a pulley which is frictionless (see figure). The acceleration of the system in terms of acceleration due to gravity g is:
Options
- Ag 2
- Bg 5
- Cg 10
- Dg
Correct answer
B. g 5
Step-by-step solution
a = m 2 − m 1 g m 1 + m 2 a = ( 6 − 4 ) g 6 + 4 = 2 g 10 a = g 5
