Answer with Explanation:
We are given that
Diameter of fighter plane=2.3 m
Radius=
a.We have to find the angular velocity in radians per second if it spins=1200 rev/min
Frequency=
1 minute=60 seconds
Angular velocity=
Angular velocity=
b.We have to find the linear speed of its tip at this angular velocity if the plane is stationary on the tarmac.

c.Centripetal acceleration=
Centripetal acceleration==
The answer is A. shorter wires
Answer:
The magnetic field of the particle is 1.5 T.
(C) is correct option.
Explanation:
Given that,
Momentum of particle 
Radius = 1.0 km
Charge of the particle 
We need to calculate the magnetic field
Using relation of radius of path in magnetic field
Here mv = p

Put the value into the formula


Hence, The magnetic field of the particle is 1.5 T.
