Okay so I have a force diagram.. gravity is the downwards force - F = mg acceleration is the horizontal force which is given by v^2/r Now what?

The acceleration is given by v^2 / r... I don't know where to get those values..

A mass of 80g is moving in a horizontal circle supported by a string 1.2m long suspended from a fixed point in the centre of the circle. The mass completes each revolution in 0.85s. Calculate the tension in the string. Relevant equations: I'm not entirely sure, but these were the ones I...
