A charge of 2 C placed in electric field of 10 N/C what will be the work done in moving charge a distance of 5. How much work is done?
Correct answer: A. 100 J
- A. 100 J
- B. 50 J
- C. 150 J
- D. 200 J
Explanation
The work done on a charge in an electric field can be calculated using the formula:Work = Charge × Electric Field × DistanceIn this case, the charge is 2 C, the electric field is 10 N/C, and the distance is 5 m. Plugging in these values into the formula:Work = 2 C × 10 N/C × 5 m= 100 N·m= 100 JTherefore, the amount of work done on the charge is 100 J. Hence, the correct answer is A) 100 J.

About Electric Field
An electric field is the force experienced per unit positive test charge, with the field of a point charge given by E = kQ/r² and directed away from positive charges or toward negative charges. Questions involve field lines, superposition and force on a charge, while electric field must be distinguished from electric potential.
