Question

a charged conductor has 4000 excess electrons find out the magnitude and the nature of the charge present on the conductor
please solve this question.
answer is 6.4 ×10 power -16 c​

Answer 1

Q=ne

where Q = charge

n = no. of electrons

e = charge on 1 electron

$e = - 1.6 \times {10}^{ - 19} coulomb$

$charge = 4000 \times 1.6 \times {10}^{ - 19}$

$charge = 6400 \times {10}^{ - 19}$

$charge = 6.4 \times {10}^{ - 16}$

nature of charge will be negative as electron has negative charge

Answer 2

q= ne

by formula ।।।।।।।।

। charged
