Answer:
0 N
Explanation:
Applying,
F = qvBsin∅................. Equation 1
Where F = Force on the charge, q = charge, v = Velocity, B = magnetic charge, ∅ = angle between the velocity and the magnetic field.
From the question,
Given: q = 4.88×10⁻⁶ C, v = 265 m/s, B = 0.0579 T, ∅ = 0°
Substitute these values into equation 1
F = ( 4.88×10⁻⁶)(265)(0.0579)(sin0)
Since sin0° = 0,
Therefore,
F = 0 N
Answer:
0.26315 s
Explanation:
The frequency of the ball tied to a string system is 3.8 rev/s.
That means in one second the ball will complete 3.8 revolutions.
The time period will be the reciprocal of this frequency
The time period is 0.26315 s
It can be also solved in the following way
The time period is 0.26315 s
Answer:
The angle of the fourth order maximum is 1.027 degrees.
Explanation:
It is given that,
Wavelength of red laser, 
Slit separation, 
We need to find the angle of the fourth order maximum. For maximum, the equation is given by :
So, the angle of the fourth order maximum is 1.027 degrees. Hence, this is the required solution.
