Aproton in a linear accelerator has a de broglie wavelength of 156 pm . part a what is the speed of the proton?

To calculate the speed of the Proton we use, de Broglie equation as

Here, m is mass of proton and its value of and h is Plank constant and its value of .

Given,   .

Substituting these values in above equation, we get

Thus, the speed of proton is 2538 m/s.
