D à Calculate the angular velocity of the electron, in radians per second. Grade Deduct Potenti tand Suhmi

Explanation / Answer

Considering my equilibrium of forces

F= mv^2/r

9*10^9*(1.6*10^-19)^2*19/(1.21*10^-10)^2= 9.1*10^-31*v^2/(1.21*10^-10)

v= 6.305*10^6 m/s

Angular velocity

w= v/r

= 6.305*10^6/(1.21*10^-10)

= 5.21*10^16 rad/s

========

Comment in case any doubt.. good luck
