Question

What is the magnitude of the acceleration of an electron that is 2.29 cm from the center of the bead? Constants | Periodic Table A small glass bead has been charged to +21.1 nC You may need the following information: Mass of a proton: 1.67 x 10 27 kg Mass of an electron: 9.11 x 10 31 kg a0636263736 Previous Answers Request Answr Submit Incorrect; Try Again: 3 attempts remaining Part D What is the direction of the acceleration of an electron that is 2.29 cm from the center of the bead? toward the bead away from the bead

Explanation / Answer

Here ,

part a) let the acceleration is a

Using second law of motion

m * a = q * E

9.11 *10^-31 * a = 9 *10^9 * 1.602 *10^-19 * 21.1 *10^-9/.0229^2

solving for a

a = 6.3 *10^16 m/s^2

the acceleration is 6.3 *10^16 m/s^2

part b)

the direction of acceleration of electron is towards the bead
