Question

If the maximum velocity v of an electron in copper wire is about 2.0x10^8 cm/s, with an uncertainty ≤ 1%, how accurately can the electron's position be determined? In other words, what is the uncertainty in the position of the electron (in meters)?

Answer 1

In one second it is 2E8 cm x 0.01 = ? and convert that answer in cm to meters.
