Answer:
300 MHz
Step-by-step explanation:
A resonance is obtained when oscillating frequency of magnetic field becomes approximately equal to intrinsic frequency of particles in the nuclei
this method is used in Nuclear Magnetic Resonance or NMR
here the resonant frequency is directly proportional to the strength of magnetic field
from the question,
initial Magnetic Field = 1.41 Tesla
Initial resonant frequency = 60 MHz
final Magnetic Field = 7.04 Tesla
final resonant frequency =
