Question

A pigeon flying around the tree changes its position from branch A to branch B and finally to branch C.
Assertion (A): Potential energy of pigeon at A > Potential energy of pigeon at B > Potential energy of pigeon at C.
Reason (R):Higher the height of the body above the ground, greater is its potential energy.

• A. A is false but R is true.
• B. A is true but R is false.
• C. Both A and R are true but is not the correct explanation of A
• D. Both A and R are true and R is the correct explanation of A.

Answer 1

The correct option is A A is false but R is true.

The correct answer is Option C, A is false but R is true.
According to the assertion potential energy of pigeon at A is highest, potential energy of pigeon at C is least and potential energy of pigeon at B has an intermediate value.
But the correct relation between potential energy and height of the body is : Higher the height of the body, greater is its potential energy.
Therefore the potential energy of pigeon at C is highest, potential energy of pigeon at A is least and potential energy of pigeon at B will have an intermediate value.
So clearly, the assertion provided is false while the reason is true.
