Electric forces and Coulombs\' law
Ex. 1 Three point charges placed on a horizontal line as shown in Fig.1. Find the net force acting on q2?
Ex.2Three charges lie along x-axis, q1=+9 µc placed at the origin and q2= +16 µc placed at x = 90 cm. Where a negative charge q3 must be placed between them such that, the net force acting on it is zero?
Ex. 3 Three point charges [q1= q3=+5µc and q2=+2µc] are located at the corners of a triangle as in Fig.
Ex.4Two point charges q1= q2=+2µc located at x = 0 and y = 30 cm and x = 0 and y = - 30 cm, respectively.
