Two bodies of mass 4 kg and 6 kg are attached to the ends of a string passing over a pulley (see fig.). The 4 kg mass is attached to the table top by another string. The tension in this string T1 is equal to (take g = 10 m/s2)
A
20 N
B
25 N
C
10.6 N
D
10 N
Answer
20 N
Explanation
Solution
T = 6 × g = 60 N
T – T1 – 4g = 0
T1 = T – 40 N = 20 N
