a thin, uniform rod, which has a length of 0.45 m and a mass of 0.080 kg. This rod lies in the plane of the paper and is attached to the floor by a hinge at point P. A uniform magnetic field of 0.25 T is directed perpendicularly into the plane of the paper. There is a current I = 3.8 A in the rod, which does not rotate clockwise or counter-clockwise. Find the angle .

2. Homework Equations

F = ILB sin(theta)

F= ma

3. The Attempt at a Solution

heres what i was thinking:

if F = ILB sin(theta) then let ma = ILBsin(theta)

so solve for theta:

arcsine(ILB/ma) = 33.0 degrees however, i was told this is wrong.
