The radial force on the particle is given by the Lorentz force. They don't give you the velocity so you have to solve for it in terms of the radius and get them to cancel.
Answer:
C.....im just typing more now because of the rule that it has to be 20 characters long
Answer:
along the lead, at right angles to the lead at the middle, and at right angles to the lead at one end.
The correct options are B and C
Let us assume the amplitude of the two sinusoidal waves be A1 and A2
As it is mentioned that the waves are identical, therefore A1=A2= a
The resultant wave of any two waves is given by the formula:
Resultant wave=
where A1 and A2 are amplitudes of waves 1 and 2 and is the angle between the waves
Now as per the formula, it is the the factor 2cos that will decide that amplitude is greater than original or not
Hence we know that maximum value of cos is when is 0 degrees
Now it is known that value of cos varies from 1 to 0 for o degrees to π/2
and the value varies from 0 to -1 for angles π/2 to π
Case 1: when =0 degree
Resultant wave R =
Case 2: When is less than 90
let us consider
Resultant wave R =
case 3:
When is less than 120
case 4: when is less than 180 degrees
the value will be 0
Hence only option b and d are correct
