Question

1⁄4i1⁄2 Name the physical quantity of unit N/C. Also mention that is it a vector or a scalar quantity \

Answer 1

Answer:

• N stands for newton which is the unit of force and C stands for coulumb which is the unit of charge then it means force per unit charge and definitely it is ELECTRIC FIELD. Let's discuss with a diffrent way. We know the dimension of force = MLT^-2 and .
• I(current)= q(charge)/t(time) i.e, the dimension of charge =IT
• Therefore the resultant dimension should be MLT^-3 I^-1
• Again electric field E = F/q=F/IT=MLT^-3 I^-1
• So it implies nothing but the electric field strenght.
• It is vector quantity.
