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

Options

A. More than 6 kg
B. Less than 6 kg.
C. Equal to 6 kg.
D. None of the above

Answer

B

Explanation

as motionis also happeing
