Two identical sphres, one positively charged and the other negativily charged are held d cm apart.If the magnitude of the charges on the two spheres are equal , find the electric potential at a point midway on the line joining the centres of the two spheres.

Two point charges of 5muC and 15 muC are placed in air 20cm apart. Find the electric potential at the middle point of the line joining the two charges.

Two point charges of +10muC and +20muC are placed in free space 2 cm apart. Find the electric potential at the middle point of the line joining the two charges.

Two charges 3 xx 10^(-8) C are located 15 cm apart. At what point on the line joining the two charges is the electric potential zero? Take the potential at infinity to be zero.

Two charges 3 xx 10^(-8) C are located 15 cm apart. At what point on the line joining the two charges is the electric potential zero? Take the potential at infinity to be zero.

Two equal and opposite charges of magnitude 0.2 mu C are 15 cm apart, the magnitude and direction of the resultant electric intensity at a point midway between the charges is

Two identical conduction spheres, one having an initial charge +Q and the other initially uncharged, are brought into contact. (a) What is the new charge on each sphere? (b) While the spheres are in contact, a positively chaged rod is moved close to one sphere, causing a redistribution of hte charges on the two spheres so the charge on hte sphere closest to the rod has a charge-Q. What is the charge to the other sphere?
