Find the electric gfield vector at p ( a
Three positive point charges q1, q2, and q3 form an isolated system. Suppose the charges have generated a property due to which like charges also attract. The charges are moving along a circle with same speed maintaining angles as shown in the figure. The charge q1 experiences a force f1 due to other two charges. Similarly, q2 experiences a force f2 and q3, a force f3. The ratio of f1 : f2 : f3 is

Five Styrofoam balls are suspended from insulating threads. Several experiments are performed on the balls and the following observations are made: (i) Ball A repels C and attracts B. (ii) Ball D attracts B and has no effect on E. (iii) A negatively charged rod attracts both A and E. An electrically neutral Styrofoam ball gets attracted if placed nearby a charged body due to induced charge. What are the charges, if any, on each ball A,B,C,D, and E?
