$\bullet$ In a cloud chamber experiment, a proton enters a uniform 0.250 T magnetic field directed perpendicular to its motion. You measure the proton's path on a photograph and find that it follows a circular arc of radius 6.13 $\mathrm{cm} .$ How fast was the proton moving?

and the given problem we confined How fast the proton is moving To find the speed, we can find it by writing an equation that is their force on a particle moving inside the magnetic field which is the charge times we recross be is equal to centripetal force That is a master and exploration which is the square divide our made our He's the radius off the particle moving in the circle of our Keir So this is our then from here we can solve for me So we will be simply que terms of antique real terms are divided by am Next up we substitute the values for a problem charge in miles In the given me antic feeling radius are so some shooting those values we get 1.6 times dented car minus 19 terms 0.250 Tesla is our romantic field times off radius which is given in them centimeters work and work it into meter So this will become 0.0 613 divided by 1.6 times 10 to the power minus 27 kilograms is the mass of the brutal and this gives us the speed off 1.53 times 10 to the power six meter for second, so this will be the speed of the problem.
