Answer:
E=930.84 N/C
Explanation:
Given that
I = 1150 W/m²
μ = 4Π x 10⁻⁷
C = 2.999 x 10⁸ m/s
E= C B
C=speed of light
B=Magnetic filed ,E=Electric filed
Power P = I A
A=Area=4πr² ,I=Intensity
E=930.84 N/C
Therefore answer is 930.84 N/C
Answer : The velocity of an electron is,
Explanation :
According to de-Broglie, the expression for wavelength is,
and,
where,
p = momentum, m = mass, v = velocity
So, the formula will be:
.............(1)
where,
h = Planck's constant =
= wavelength =
m = mass of electron =
v = velocity of electron = ?
Now put all the given values in formula 1, we get:
Thus, the velocity of an electron is,
