Question

A glass rod rubbed with silk acquires a charge of 8 ×10^-12 coulomb.The no.of electrons it has gained or lost

Answer 1

Answer:

we apply the formula q equals to ne

then charge is given 8*10the power-12

we find n

e is 1.6*10the power -19

so q equals to ne

8*10 the power minus 19 equals to n*1.6*10 the power minus 19

so n equals to 8*10 power -12/1.6*10power -19

now n equals to 8* 10 power +7/1.6

then the answer is 5*10 power +7

thanks follow me
