Thread: [Physics] need to find an angle

A plumb bob does not hang exactly along a line directed to the center of the Earth's rotation. How much does the plumb bob deviate from a radial line at 38.0° north latitude? Assume that the Earth is spherical.

the method to solve this eludes me... any help?

nevermind, past due date. i was very close, but i miscalculated the radial acceleration of the earth @ 38 N
