In the arrangement shown, the pulleys are fixed and ideal, the strings are light, m 1 > m 2 , and S is a spring balance which is itself massless. The reading of S (in units of mass) is –
A
m 1 – m 2
B
(m 1 + m 2 )
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Acceleration of system = 
g
Tension in string = 
g
reading of spring balance is T.
