I've tried to work put the variables into the formula: m*v^2/r. But it didn't work.

2*0.83^2/1.05 = 1.3 <That answer did not look correct to me. I probably did something wrong. But don't remember what.

Have you thought about the Fc=mw^2R equation? That might help.
A centripetal force is a force that acts on an object moving in a circular path, always directed towards the center of the circle.
The centripetal force can be calculated using the formula F = mv^2/r, where F is the force, m is the mass of the object, v is the velocity, and r is the radius of the circular path.
Some common examples of centripetal force include a car turning a corner, a satellite orbiting around the Earth, and a ball on a string being swung in a circular motion.
If there is not enough centripetal force, the object will not be able to maintain its circular path and will instead move in a straight line. This can result in the object veering off course or losing control.
To solve a centripetal force problem, you will need to identify the known values, such as mass, velocity, and radius, and plug them into the formula F = mv^2/r. Then, you can solve for the unknown value, which is typically the centripetal force. It is also important to pay attention to the units of measurement and use consistent units throughout the calculation.
