How many electrons must you take away from a neutral object to give it a net charge of 2.4 nC?

Homework Answers

Answer #1

In a neutral object there is equal number of proton and electron

Charge of electron = -1.6× 10-19C ( negative charge)

Charge of proton = 1.6 × 10-19C ( positive charge)

To calculate how many number electrons are in 2.4nC, divide it with one electron charge

Number of electrons in 2.4nC (2.4× 10-9C) = 2.4×10-9/1.6×10-19 = 1.5×1010 number

If we remove 1.5 × 1010 number of electrons from a neutral object. -2.4nc charge will lose and object get +2.4 nC net charge.
