Question

A student slides down a slide at recess. After getting off the slide he goes to cross the monkey bars. As he touches the metal of the monkey bars, he gets a shock. How did the electric charge transfer from the slide to his body
A. Friction
B. Conduction
C. Induction
D. Polarization

Answer 1

Answer:

Option-(A,B): First the frictional forces are there and then the conduction process happens.While, the whole process takes place in two steps, so we will try to evaluate in the following way.

Explanation:

1. When the little kid slides down the slide, there is a net contact between his body and the structures surface.As, the force of friction exists between the two leading it to create some charge particles which are then present of the kid's body and clothes.
2. When he reached out to touch the metal which is a part of the monkey's bar he gets a shock and it is just because that the charges present are now able to move across his body towards the zero potential which is the ground.

Answer 2

Conduction is the answer
