Student ties 0.060kg lead fishing weight to the end of a piece of string and whirls it around in a horizontal circle.if the radius of the circle is 0.30m and the object move with a speed of 2.0m/s..what is the horizontel component of d force that directs the lead weight towards the centre of the circle? What is the tension of the string??

centripetal and tension force= mv^2/r

it is a slight more complicated on tension: you have the horizontal centripetal force, and the weight at ninety degrees down. Add them as vectors.
