Question

1. Rubbing a comb on hair makes the comb
get - 0.4C. (a) Find which material has
lost electron and which one gained it.
(b) Find how many electrons are
transferred in this process.​

Answer 1

Answer:

solved

Explanation:

(a) Find which material has

lost electron and which one gained it.

hair lost

comb gained

(b) Find how many electrons are

transferred in this process.​

charge of electron = 1.602 x 10∧-19C

number of electrons   transferred in this process = N

N = 0.4 ÷ 1.602 x 10∧-19 = 0.25x10∧19
