Question

calculate the net charge on a substance consisting of 5×10^14 electrons
​

Answer 1

Answer:

charge on 1 electron = -1.6x10^(-19) (^ refers to power)

since electron is negatively charged body,so value is negative

no. of electrons = 5x10^(14)

Net Charge ={ (-1.6)x10^(-19) }x{ 5x10^(14) }

= -8x10^(-5) Coulombs
