Assertion (A) : The weight of a body changes with altitude.
Reason (R ): The accelaration due to gravity changes with altitude.

Text Solution

Verified by Experts

The correct Answer is:
A
The weight of a body changes from place to place with altitude. So , A is correct.
Weight = mass xx accelaration due to gravity.
The value of acceleration due to gravity changes with altitude. So, the weight also changes. So, R is also correct and R is the correct explanation of A.
