"A 5N weight is attached by a string to the ceiling of a train carriage. As the train accelerates out of a station along a horizontal track the string makes an angle of 6 degrees to the vertical."

A) What force causes the weight to accelerate?

B) Resolve the forces on the weight vertically to find the tension in the string

C) find the acceleration of the train.
