Question

A barometer kept in a stationary elevator reads 76 cm. If the elevator starts accelerating up, the reading in barometer will be:

• A. Zero
• B. Equal to 76 cm
• C. More than 76 cm
• D. Less than 76 cm

Answer 1

The correct option is D Less than 76 cm

Since the elevator is accelerating up, so, the force will act in the downward direction.

Therefore, the reading in the barometer will be less than 76 cm
