Which of the following two statements is true? A or B? _________A. Most electrons will go into the knob and down to the earth.B. Some electrons will go from the earth through the knob and into the man.25. Why are shocks worse when you touch conductors rather than insulators? 26. If you take your hat off on a dry winter day. sometimes your hair will stand up. Explain this phenomenon._______________________________________________________________________________________________ **Title: John Travoltage****Description:**The image is from the "John Travoltage" simulation on the PhET website by the University of Colorado Boulder. It illustrates the concept of static electricity and charge transfer.**Visual Elements:**1. **Main Character:** A character dressed in black appears to be accumulating static charge as he shuffles across a carpet. Blue circles are depicted, representing the electrons being transferred to his body.2. **Setting:** The scene shows a simple indoor environment with a window in the background and a wooden door ahead of the character. The character is extending a finger towards the metal doorknob, suggesting the point of potential static discharge.3. **Educational Purpose:** The simulation demonstrates how static electricity can occur from friction (shuffling feet on a carpet) and how it can lead to a spark or shock when a charged object (like a person) touches a conductor (such as a metal doorknob).PhET simulations are designed to enhance understanding of scientific concepts through interactive elements that allow users to explore and visualize different phenomena. The image is from a physics simulation titled "John Travoltage," available on the PhET Interactive Simulations website at phet.colorado.edu. It shows a silhouette of a person walking on a rug, reaching for a door handle, which is likely used to demonstrate static electricity concepts. In the background, there is a window with an outdoor scene. Key elements include:- A representation of static electricity as the person walks on the rug.- The hand approaching a metal door handle, potentially illustrating the concept of electric discharge or a spark.This simulation is an interactive tool for exploring the principles of static charge, buildup, and discharge, engaging users in understanding fundamental electrostatic interactions.

Electrons are the negtive charges & having a charge of -1.6*10-19C. When person touchesthe knob electrons will transferred from person to knob as electron flow from highly concentrated region (person body) to low concentrated region (knob) and finally get transferred to earth. As we know earth can absorb enormous charge inside it and the potential become zero finally. Option A is correct.
