The tension in a 2 m length of string that whirls a 1 kg mass at 4 m/s in a horizontal circle is calculated to be 8 N. How do you alculate the tension for the following case: twice the mass?

The tension in the string is balanced by the centripetal force.
This is given by
This is equal to
So you can see that, without doing any calculations, doubling
