AHH this problem is driving me nuts!
A small container of water is placed on a carousel inside a microwave oven, at a radius of 13.5 cm from the center. The turntable rotates steadily, turning through one revolution each 6.50 s. What angle does the water surface make with the horizontal?

I got an answer of 0.76212865 deg. but the online hw thing says that I'm within 10% of the correct answer. Please help...THANK YOU!!
