Question

To study the properties of various particles, you can accelerate the particles with electric fields. A positron is a particle with the same mass as an electron but the opposite charge (+e). If a positron is accelerated by a constant electric field of magnitude 340 N/C, find the following.

To study the properties of various particles, you can accelerate the particles with electric fields. A positron is a particle with the same mass as an electron but the opposite charge (+e). If a positron is accelerated by a constant electric field of magnitude 340 N/C, find the following. Find the acceleration of the positron. Find the positron's speed after 8.70 times 10-9 s. Assume that the positron started from rest.

Explanation / Answer

a) F = ma = qE

9.1 * 10^-31 * a = 1.6*10^-19 * 340

a = 5.98 * 10^13 m/s^2

b) speed = u +at

= 0 + 5.98 * 10^13 * 8.7 * 10^-9

= 5.2 * 10^5 m/s
