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)
Should I still go?
