Question

A man of mass '$m$' is on the floor of a lift and lift is moving up with acceleration ‘$a$’ then
a) normal reaction is more than his weight by ma
b) man appears to be heavier by ($\frac{a}{g}$) times his true weight

• A. a & b are correct
• B. a & b are wrong
• C. a is correct & b is wrong
• D. a is wrong & b is correct

Answer 1

The correct option is A a & b are correct

Refer to the concept (ii), Since lift accelerates upwards the pseudo force will act downwards and the net normal reaction will increase by $ma$
