Question

A proton is traveling horizontally to the right at 4.20×10^6 m/s. Find (a) the magnitude and (b) direction of the weakest electric field that can bring the proton uniformly to rest over a distance of 3.10 cm. C) How much time does it take the proton to stop after entering the field? D) What minimum field ((a) magnitude and (b) direction) would be needed to stop an electron under the conditions of part (a)? E) What is the angle counterclockwise from the left direction?

Step 1

Given: Initial velocity of proton, \(v_0 = 4.20 \times 10^6 \, \text{m/s}\) Acceleration, \(a = -2.845 \times 10^{14} \, \text{m/s}^2\) (negative sign indicates retardation) We can use the equation \(v = v_0 + at\) where \(v\) is the final velocity (0 m/s in this Show more…
