Given data
Ex = Ey = 0
Ez=(4.3V/m)cos(π×10¹⁵s⁻¹)(t-x/c)
To find
The amplitude of the magnetic field component
Solution
The electric field is given by:
Ez=(4.3V/m)cos(π×10¹⁵s⁻¹)(t-x/c)
Where Em=4.3 V/m
The magnitude of magnetic field is given by:
Where Em is amplitude of electric field and c is speed of light.
Substitute the given values
So
Answer:
Explanation:
As we know the , equation of time period for simple pendulum ,
T = 2*pi*
hence putting values we get ,
