In an apparatus, the electric field was found to oscillate with an amplitude of 18Vm-1. The magnitude of the oscillating magnetic field will be

Please find this answer

What is B and E?
  • 2
B-Magnetic field
E-Electric field
  • 2
Use c=E/B ~B=E/C C=speed of light E=18v/m
  • -1
  • amplitude =18 V/m
  • B0=E0/c        [here c is the velocity of light]
  • {B0= 18/3*10^-8}
  • ​​​​​​​
  • 3
so finally you will get 6*10^-8
HOPE THIS WILL HELP YOU.....
