Calculate the electric field at point A, B and C as shown in figure.

Question

Two point charges q₁ and q₂ of magnitude 10^-8C and -10^-8C, respectively, are placed 0.1 m apart.

Answer 1

Electric Field at any point is defined as the electric force experienced by a unit positive test charge due to another charge at a distance r. This Electric Field is a vector

( the negative sign signifies its attractive field or in other words can be inverted by reversing the direction of the vector.)
