A body has a positive charge of 8*10^-19c.it has
a)An excess of 5 electron b)a deficiency of 5 electrons
c)an excess of 8 electron d)a deficiency of 8 electrons
The answer is that the body has deficiency of 5 electrons. Because the positve charge is formed when electrons are given away from the body. Never the positive charges are transferred..
Also 8*10^-19C is a multiple of 5*charge of 1 electron..
Hence (b) is the correct option.
it shud be (b).
because there is a positive charge , the body shud have less electron than protons and thus there is deficiency. and there is 1.6 * 10-19 C charge on each electron so there are 5 less electrons.
body has charge Q=8*10-19 SO FROM Q=Ne n=q/e 8*10-19/1.6*10-19 =5 deficiency electrons
