Do your best Q1. If a charged body A having charge +2q touched another uncharged body B . Then A touched another charged body C having charge +2q . Find the force between A and C if they are separated by 1 m. Q2. A system has two charges Q1 = 3μC and Q2 = -3μC . The coordinates of Q1 and Q2 are (10,4,2)m and (5,-9,-10)m respectively. (a) Name the system. (b) Find the net charge of the system. (c) Find the dipole moment of the system. Q3. find the force between the total negative and the total positive charge extracted from 100 ml of water and then kept at 10 cm apart. Q4. Find the nature and magnitude of x so that "P" is a null point. Q6. find the amount of two equal charges separated by 10 cm so that the force between them can support the weight of a 40 kg person.
