Final answer:
Approximately 4 J of work is required to move a 2 c (coulombs) point charge 2 m in a 10 V/m uniform electric field.
Step-by-step explanation:
The work done to move a point charge in a uniform electric field can be calculated using the formula:
Work = force x distance
In this case, the force experienced by the point charge is given by:
Force = charge x electric field
Given that the charge is 2 c (coulombs) and the distance is 2 m, and the electric field is 10 V/m, we can substitute these values into the formula to find the work:
Work = (2 c) x (10 V/m) x (2 m) = 4 cV = 4 J
Therefore, approximately 4 J of work is required to move the 2 c point charge 2 m in a 10 V/m uniform electric field.
