the side of an equilateral triangle is 20 cm identical charges of 1.5x 10^-5 C are placed at each of the 3 vertices. If a test charge is placed at the middle of equilateral triangle what force would be acting on the test charge?
A test charge of +2 x 10^-7 C is located 5 cm to the right of a charge of +1 x 10^-6 C and 10 cm to the left of a charge of -1x10^-6 C. The three charges lie on a straight line. Find the force on the test charge? with solution
