2. The dryer sheet is negatively charged and your hand is positively charged

Answer:

2. The dryer sheet is negatively charged and your hand is positively charged.

4. The dryer sheet and your hand have opposite charges.

Explanation:

As we know that electrostatic force between two charges is given by

[tex]F = \frac{kq_1q_2}{r^2}[/tex]

here we know that two charges here are of similar type i.e. either both are positive or both are negative then in that case the force between them is repulsive force and if the charges are of opposite sign then the electrostatic force between two charges are attraction type of force.

So here If our hand is attracted towards the dryer sheet then our hand and dryer sheet must have opposite charges due to which they are attracted.

Also we know that the electron affinity of dryer sheet is more due to which it has tendency not to lose the electron so here we can say dryer sheet is negatively charge and hand is positively charged
