1.	Two opposite charges each of magnitude 10^-9C are separated by distance 9m . Electric potential at a point Midway between them is
Answer» Explanation: TWO opposite charges with similar value at some distance makes a dipole. And, here given two charges makes a dipole. For dipole, electric potential V=pcosθ/4πε0r²(where θ is the angle line that CONNECT given POINT makes with MIDPOINT of dipole make with dipole axis.) for the point in the midway, θ will be 90 so cosθ will be zero. thus, V=0.

Answer»

Explanation:

TWO opposite charges with similar value at some distance makes a dipole.

And, here given two charges makes a dipole.

For dipole, electric potential V=pcosθ/4πε0r²(where θ is the angle line that CONNECT given POINT makes with MIDPOINT of dipole make with dipole axis.)

for the point in the midway, θ will be 90 so cosθ will be zero. thus, V=0.
