An electron has a linear momentum of 4.0 × 10-25 kg m s-1 . What is the order of magnitude ofthe kinetic energy of the electron?
Question
Solution 1
To find the order of magnitude of the kinetic energy of the electron, we can use the formula for kinetic energy:
K.E. = 1/2 mv^2
However, we don't have the velocity (v) of the electron. We do have the linear momentum (p), which is related to the mass (m) and velocity (v) by the formula:
p = mv
