Solution

The correct options are
B magnetic field at the site of nucleus is increased by 32 times
C angular momentum of electron is changed
Magnetic field at centre (site of nucleus):
B=μ0I2r=μ0qf2r=μ0qv2r×2πrBα1r2 and Bv
B1n5
B1B2=(2)5(1)5
(since, n1=1 to n2=2)
B1=32B2
Also, mvr=n.h2π,therefore angular momentum is changed by h2π.
