A) \[{{W}_{A}}={{W}_{B}}={{W}_{C}}\]
B) \[{{W}_{A}}=\text{ }{{W}_{B}}={{W}_{C}}=\text{ }0\]
C) \[{{W}_{A}}>W>{{W}_{C}}\]
D) \[{{W}_{A}}<{{W}_{B}}<{{W}_{C}}\]
Correct Answer: B
Solution :
When a positive charge is moved from one point to another in an electric or magnetic field, then under the influence of the field force acts on the particle and an external agent will have to do work against this force. But in the given case the charge moves under influence of no field, hence it does not experience any force therefore, no work is done. \[{{W}_{A}}={{W}_{B}}={{W}_{C}}=0\]You need to login to perform this action.
