A uniform magnetic field is decreasing at a rate of 0.23

A uniform magnetic field is decreasing at a rate of 0.23 T/s. What is the magnitude of the induced electric field at a distance of 3.0 cm from the center of the magnetic field?
Induced emf= e =Or,e =Or, e = as,[as, or,or, So, here, induced electric field,E=or, ANS:Induced electric field at a distance 3.0cm is
