    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)
    B.mN
    C.N
    D.MN
