Assertion : If we plot potential versus ...

Assertion : If we plot potential versus x- coordinate graph along the x-axis, then field strength is zero where slope of `V -x` graph is zero.
Reason : If potential is function of x- only then
`E = - (dV)/(dx)`

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explantion of Assertion.

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
`E = - [(delV)/(del_(x)) hati + (delV)/(del_(y)) hatj +(del V)/(del_(z))hatk]`
`(delV)/(delX) = 0` does not mean field strength is zero.
Becouse it also depends on `(delV)/(del_(y))` and `(delV)/(del_(z))`.
