Q. Which of the following donot depend on the choice of zero potential or zero potential energy ?

question no 8 C

For question no 4 V(x)=\frac{kqd}{x(d-x)}

Where d is distance b/w A&B

Now find V'(x) using sign scheme you will see that V(x) is decreasing then increasing

Potential at a point and potential energy of a two-charge system do not depend on the choice of zero potential .

Bro for this q3 ans is given that none options are correct.

Yes ,i also did this but answer is given BD

Yes bro share solution

Bro for question no 3 no option is correct as

Clearly you can see in the pic that if E=0 that does not imply V=0

And if V=0 does not imply E=0

Potential due a charge q At a distance R from it , given by \displaystyle \frac{q}{4π \epsilon_0 R}=\frac{ΔW}{q}

Given figure is a half circle

Bro why you didn't calculate potential at point P and then Va-Vp, Vb-Vp..etc ?

Assume p is at very far distance from the q charge

V_p=0
