shown in the diagram?
A. L = W; F < D
B. L = W; F = D
C. L = W = F = D
D. L = W; F > D
A. L = W; F < D

E=mcθ
where E is the energy added,m is the mass,c is the specfic heat capacity and θ is the change in temprature.
making m subject u get E/c<span>θ=m
</span><span>θ=(30-20)=10</span><span>
plugging the values we get :

Answer:
Explanation:
As we know that when charge particle is projected in perpendicular magnetic field then the radius of the charge particle is given as
now we have
since here radius of proton and electron will be same
so we will have
so we have
given that
so we have
