A balloon, initially neutral, is rubbed with fur until it acquires a net charge of -0.60nC.
assuming that only electrons are transferred, were electrons removed from the balloon or added to it?
Answers
Therefore 3.75 × 10^9 electrons are added to the balloon.
Given : A balloon, initially neutral, is rubbed with fur until it acquires a net charge of -0.60nC.
To check : The electrons removed from the balloon or added to it.
solution : as it is given that a balloon is rubbed with fur until it acquires a net charge of -0.6 nC. since net charge acquired by balloon is negative, electrons are added to the balloon.
as charge on each electron = 1.6 × 10^-19 C
so number of electrons added to balloon = net charge on balloon/charge on each balloon
= (0.6 × 10^-9)/(1.6 × 10^-19)
= 3.75 × 10^9
Therefore 3.75 × 10^9 electrons are added to the balloon.

Answer:
Explanation:
As there is a loss of charge(0.60nC) on rubbing,we can conclude that electrons were removed from it.
The charge would have been positive,if electrons were added.Hope you understood
