Answer:
The minimum charge required to pick up the tissue paper is 44.1 nC.
Step-by-step explanation:
1-The force of attraction between the ruler and tissue paper is given by Coulomb's Law of Electrostatics which is as
Here
- F is the force required to pick the tissue paper up. The minimum force required is equal to the weight of tissue paper. which is given in SI as
- k is the constant value which is given as
is the charge on the ruler which is -16μC.
is the charge on the tissue paper which is to be calculated.- r is the distance between two bodies which is given as 3.60 cm.
Putting values and solving in the equation gives
