Question

The electric field strength in an electromagnetic wave is 10v/m the magnitude of magnetic field strength in tesla will be

Answer 1

100v/m is the answer

Answer 2

The magnitude of magnetic field strength in tesla will be 3.3 × $10^{-8}$ T Given : The electric field strength in an electromagnetic wave is 10v/m

To Find : The magnitude of magnetic field strength in tesla

Solution : The magnitude of magnetic field strength in tesla will be 3.3 × $10^{-8}$ T

It is given that the electric field strength in an electromagnetic wave is 10v/m

we have to find the magnitude of magnetic field strength in tesla

Now we know that

$B_{o} = \frac{E_{o} }{c}$

where $B_{o}$ is magnetic field strength

$E_{o}$ is electric field strength

and c is speed of the light

It is given that $E_{o}$ is 10 v/m

speed of the light (c) is $3$ × $10^{8}$ m/s

So

$B_{o}$ = $\frac{10}{(3)10^{8} }$

= 3.3 × $10^{-8}$ T

So the magnitude of magnetic field strength in tesla will be 3.3 × $10^{-8}$ T
