Question

the electron are accelrated to a speed of 2.40*10^7 in 1.8*10^-9, the force experinced by an electron ?

Answer 1

Force = mass × acceleration

To find acceleration, we can divide the speed by the time it took:

acceleration = 2.40×10^7 / 1.8×10^-9

acceleration = 1.33×10^16

the mass is equal to the mass of an electron

force = (9.11×10^-31)(1.33×10^16)

force = 1.21×10^-14 N
