A charge of Q creates an electric field of E= 100 N/C at a distance of r = 0.1 m. If two charges Q1 = 0.8Q and Q2 = -1.4Q are separated by a distance of ℓ = 0.6 meters, what is the magnitude of the electric field at point P that is at the middle of the charges?

A test charge of 4.4 x 10^-6 C is placed 35496 m away from an unknown charge. The magnitude of the electric field at this location is 53.8 N/C. What is the unknown charge?

A test charge of + 4 µC is at a field-point P where the electric field E due to other charges is directed to the right and has a magnitude |E| = 4 x 106 N/C. If the test charge is replaced with a charge of - 4 µC, the electric field at P gets modified to E' as : O E' = E O E = (3/4) E O E' = (4/3) E E' = - E
