Homework Help: Physics

Posted by Sui on Sunday, October 2, 2011 at 4:40pm.

Nuclear fusion reactions require that positively charged nuclei be brought into close proximity, against the electrostatic repulsion. As a simple example, suppose a proton is fired at a second, stationary proton from a large distance away. What kinetic energy must be given to the moving proton to get it to come within 1.00e10-15 m of the target? Assume that there is a head-on collision and that the target is fixed in place.

Ok, so I'm thinking to use:

= 2.31e-13

Does that make sense? Am I doing something wrong?
