Question

1.On rubbing glass rod with silk cloth it is found hat 500 electrons transfer from glassrod to silk cloth.Nature of charge on glass rod and silk cloth respectively will be:
a.positive, positive
b.negative, positive
c.positive, negative
d.negative,negative

2.In the above question magnitude of charge in coulomb on glass rod will be:
a.8.0x10^-19
b.80.0x10^-19
c.8.0x10^-17
d.80.0x10^-17​

Answer 1

Explanation:

i). answer is c

ii) answer is b

bcz we know Q= ne

so given is number of electron (n)=500

and charge on 1 electron is 1.6(10^-19)

put all these in Q = ne

we get 80 ( 10^-19)

Answer 2

Answer:

I guess it's (b)
