1. Hooke's law states that the force F in a spring extended by a length x is given by F= -kx . Calculate the dimension of spring constant k.
2. The force between two wires 1,2 length 1 meters separated by a distance d meters and carrying currents I1 AND I2 Amperes is given by :
[tex]F = \frac{kI_1I_2}{d}[/tex] .
find (a.) the units of constant k
(b.) dimension of k
