(a) How many electorns are in 1C of negative charge?
(b) Which is the true test of electrification: attraction or repulsion?
(c ) Can a body have a charge of `0.8xx10^(-19)C` ?

Text Solution

Verified by Experts

(a) `q="ne"`
`n=(q)/(e )=(1)/(1.6xx10^(-19))=6.25xx10^(18)`
(b) Repulsion. As charged body can attarct uncharged body.
(c ) No, as charge is quantized.

    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?
