Respuesta :
A point's potential is 400 V.
The electric potential between two identical charged particles is 300 V at a point halfway between them. Potential V = 300 volts
Let 2r be the distance between the charges.
If the potential is 25% of the way from one particle to the other.
We must compute the distance between the charges.
d=2r*25/100= r/2
We must compute the new potential.
Using the potential formula once more
V=300*( 3+1/3)
V=400V.
Hence, potential is 400 V.
The complete question is-
The electric potential at a point that is halfway between two identical charged particles is 300 V. What is the potential at a point that is 25% of the way from one particle to the other?
