Question

A charged balloon attracts to a wall because of 1. Electrostatic force 2. Magnetic force
3. Muscular force 4.Gravitational force

Answer 1

Answer: 1. Electrostatic force

Explanation: When an element such as this balloon is rubbed against a comb or a surface,

it induces negative charge leaving the comb or the surface positiveliy charged.

When this negatively charged balloon is moved against a wall,

It repels the electrons of the wall and induces positive charge on it.

Hence, the positive and negative charges attract each other.

And thus a charged balloon can attract a wall.
