Question

What is the speed of an electron traveling 32 cm in 2 ns?

Answer 1

Speed,
`v=1.6* 10^8\ m/s`

Step-by-step explanation:

Given that,

Distance covered by the electron, d = 32 cm = 0.32 m

Time, t = 2 ns

We need to find the speed of an electron. Speed is equal to distance covered divided by time. So,

`v=(0.32)/(2* 10^(-9))\\\\v=1.6* 10^8\ m/s`

So, the speed of the electron is
`1.6* 10^8\ m/s`.
