B = 0.018 T Ans,
Since, it is moving in a circular path, thus, centripetal force will act on it i.e.
F =
where, m is the mass of the object, v is the velocity and r is the radius of circular path.
And, since a positive charge is moving, it will create magnetic force which is equal to F = qvB
where q is the charge, v is the velocity of the particle and B is the magnetic field.
Now, the two forces will be equal,
i.e. = qvB
⇒
= qB
⇒B =

use q = 1.6 * 10^ -19
⇒ B = 0.018 T

Answer:
- R = ( 4.831 m , 1.469 m )
- Magnitude of R = 5.049 m
- Direction of R relative to the x axis= 16°54'33'
Explanation:
Knowing the magnitude and directions relative to the x axis, we can find the Cartesian representation of the vectors using the formula
where its the magnitude and θ.
So, for our vectors, we will have:
and
Now, we can take the sum of the vectors
This is R in Cartesian representation, now, to find the magnitude we can use the Pythagorean theorem
To find the direction, we can use
As we are in the first quadrant, this is relative to the x axis.
Answer:
Solution given:
frequency[f]=x
velocity[V]=15000m/s
wave length=59m
we have
wave length=
59m=
x==254.Hz
frequency=254Hz
