Question

A person is installing a ceiling fan and doesn't realize that the circuit is live. i.e. There is a potential difference across the wires that the person hending. In which of the following situations is the person most at risk to receive a potentially fatal electric shock? Suppose you are standing at the Earth's equator, which one of the following statements best describes the direction of the Earth's magnetic field at the location? Calculate an electron initially moving north in a region where there is a magnetic field that as also directed . Which one of the following statements is correct concerning the direction of the magnetic force on the electron?

Explanation / Answer

#1

when the hands are wet the electric current will easily flow through it so it is the most risky situation

#2

at equator the earth magnetic field is always directed horizontally

#3

Since the field and velocity are parallel to each other so there will be no magnetic force on electron
