An electron has momentum that is 90 % larger than its classical momentum. Find speed of electron.
Classical momentum Relativistic momentum Here m is effective mass
Given, Speed of electron v = 0.85 c.
ways and rules of finding moment of force
It is the force that the field would exert on any unit magnetic pole placed in the field. It is also known as magnetic force.
In case of dextro rotation we consider angle positive & in case of leavo rotatory we consider negative. But in Maths Rotation to left increases value of angle ( + ve)& towards righ
