7. Holding the separation constant, repeat steps 2 and 3, measuring the current for about ~10 different masses, up to a maximum of 100 mg. Record your data in a table of the form shown in Table.l.

Using Eq. 3, determine the theoretical expression for the slope. Using this expression, solve for the magnetic permeability constant, my in terms of the slope and hence calculate pg
