What Is the Peak Value of the E-Field If the Magnetic Field Is 2 x 10^-7 T?

AI Thread Summary
The peak value of the electric field (E) in an electromagnetic wave can be calculated using the formula E = cB, where c is the speed of light. Given a magnetic field (B) of 2 x 10^-7 T, the calculation yields E = 60 N/C. The initial query confirms the correctness of this calculation. The response affirms that the calculation is accurate. The discussion effectively clarifies the relationship between the electric and magnetic fields in electromagnetic waves.

Hi,

My Question:

If the peak value of the magnetic field of an EM wave is 2 x 10^-7 T. Calculate the peak value of the E-field.

Work:

C=E/B so,

3*10^8 m/s=(E)/(2*10^-7 T)
(3*10^8 m/s)(2*10^-7 T)=E

E= 60 N/C

Is this right ?

Thank You

Hi,

I'm sorry but I just wanted to know if I did this problem correctly

Thank You
 
Yea that's correct.

E = CB

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
