Units of measuremtn question

    • Thread Starter

    I'm not sure how to answer this question so any help would be appreciated.

    A student determines a value for a force using the formula F = kIL (L being lowercase).

    k is a constant with units of NA^-1 m^-1
    I is current measured in mA
    L is length measured in mm

    The student uses these numbers directly in their calculation.
    What will be the units of the force from that calculation?

    A. uN (u being micro)
