help me solve pls....pls prioritize (b)

Axis
XI X
20.0 cm
40.0 cm
A rectangular wire with width of 20.0 cm and length
of 40.0 cm, carries a current of 3 Amperes. The wire
is in the x-y plane and is therefore perpendicular to
a uniform magnetic field with magnitude of 2.50 Tesla.
(a) Calculate the net force that the magnetic field
exerts on the coil.
(b) The coil is rotated through a 30 degree angle
about the axis shown, with the left side coming out
of the plane of the figure and the right side going
into the plane. Calculate the net force that the
magnetic field now exerts on the coil. (Hint: In order
to help visualize this three-dimensional problem,
make a careful drawing of the coil as viewed along
the rotation axis.)
