alleryElectric field strength at a point is defined as force per unit:
Amass
BCHARGE on a small test charge placed at that point
Cvolume
Dtime
Answer & Solution
Correct answer: B. CHARGE on a small test charge placed at that point
E = F/q_test.
**Direction:** along the force on a positive test charge. SI unit: N/C or V/m.
