What is the acceleration of an object having charge 2μC and mass 2 g moving through electric field strength 20 N/C?
Correct answer: B. 2 cm/s^2
- A. 4 cm/s2
- B. 2 cm/s^2
- C. 40 cm/s2
- D. 20 cm/s2
Explanation
2x10-6 x 20 / 2x10-3 = 0.02 m/s2 x100 = 2cm/s2

About Electric Field Intensity
Electric field intensity is the force acting per unit positive test charge, with direction set by the force on that charge. Work includes fields of point charges, vector superposition, field lines and the relation between field and electric potential. Field intensity must be distinguished from electric force and potential.
