Question

A body is projected vertically upward with speed $10m/s$ and other at same time with same speed in downward direction form the top of a tower. The magnitude of acceleration of first body with respect to second is {take $g=10m/s^2$}

• A. Zero
• B. $5m/s^2$
• C. $10m/s^2$
• D. $20m/s^2$

Answer 1

The correct option is A Zero

The magnitude of acceleration is taken place with $g$ and second body has a downward acceleration with respective of $g.$

This denotes first body and utilize with same acceleration and no one is accelerating with respect to another$.$

The magnitude of acceleration is zero because there is no change in velocity by practical$.$ it is ultimately $0$ by perfect measurement$.$

Hence,

option $\left(A\right)$ is correct answer.
