Question

Statement I: When you are accelerating upwards with some acceleration in a elevator your measured weight will be more than your actual weight.
Statement II: Normal force on you will be more than your weight in any elevator.

• A. Statement I is true, Statement II is true, Statement II is the correct explanation for statement I
• B. Statement I is true, Statement II is true, statement II is not the correct explanation for statement I
• C. Statement I is true, Statement II is false
• D. Statement I is false, Statement II is true

Answer 1

The correct option is C Statement I is true, Statement II is false

While moving up with some acceleration in a lift, pseudo force acts downwards.
Hence $N=mg+ma$
$\Rightarrow N>mg$
Statement I is true.
Statement II is false, as $N>mg$ only when lift is moving up with acceleration or moving down with deceleration.
