Answer:
Part a)
Part b)
Explanation:
Part a)
Electric field due to large sheet is given as
now the electric field is given as
Now acceleration of an electron due to this electric field is given as
Now work done on the electron due to this electric field
So work done is given as
Part b)
Now we know that work done by all forces = change in kinetic energy of the electron
so we will have
Answer:
θ = 41.80°
Explanation:
Given that
Mach number M= 1.5
We know that
M = u/c
Where c is the velocity of sound and u is the speed of plane
c= 340 m/s
So
u = 1.5 x 340 m/s
u = 510 m/s
We know that
Now by putting the values
θ = 41.80°
So the angle will be 41.80°.
