A 85kg man in a lift accelerating upward at 1.8m/s2 stands on a scale. What is the reading? (Take g\=10m/s2)
Scale reads normal force. As per NCERT Chapter 3, equations v=u+at, s=ut+½at², v²=u²+2as describe uniformly accelerated motion. Applying correct signs and units gives 1003 N as the result, so option B is correct.
