Two positively charged particles q1 = 2C and q2 = 2C are separated by distance d = 1.0 m. Calculate the total electric potential energy of 3 particles when a charged particle, q3 = 2C, is placed at ¼ the distance between the two particles q1 and q2.
Recently we were padding on a boat in a sea. Surprisingly we saw gleaming points in water during padding. Would you explain about this.
