Two masses of 1kg and 5kg are attached to the ends of a massless string passing over a pulley of negligible weight. The pulley itself is attached to a light spring balance as shown in figure. The masses start moving during this interval, the reading of spring balance will be:

Options

A. `6 kg`
B. less than `6 kg`
C. more than `6 kg`
D. may be more or less than `6kg`

Answer

B

Explanation

`m_(1)g-T=m_(1)a,T-m_(2)g=m_(2)a,T^(1)=2T`
