Is the frictional force the same as the applied force when the net force equals zero?

Physics

DerKrebs [107]2 years ago

Answer:

Since the net force is to the right (in the direction of the applied force), then the applied force must be greater than the friction force. The friction force can be determined using an understanding of net force as the vector sum of all the forces.

A proton moving along the positive x-axis enters a uniform magnetic field which is directed along the
SSSSS [86.1K]

Answer: The force acting on the proton of charge ​1.5 x10-19 C moving with velocity 1.5 x10-19 C under the influence of a magnetic field of 0.7 T will be 3.15×10^-13 N.

Explanation: To find the answer we need to know more about the Lorentz magnetic force.

<h3>What is the Lorentz magnetic force acting on the proton?</h3>
  • Consider a proton of charge q moving with a velocity v in a magnetic field, then the Lorentz magnetic force exerted on the proton can be expressed as,

                                  F= q (v× B)

                               F= qvBsin\alpha  where, \alpha is the angle between v and B.

  • In the question, it is given that,

                                B=0.7 T\\q=1.5*10^{-19}C\\v= 3*10^{6}m/s.\\\alpha =90 degree.\\ because, from the question it is clear that the proton is moving along x axis and the magnetic field is along the y axis.

  • Thus, we can find the force acting on the proton as,

                      F=qvBsin\alpha =1.5*10^{-19}C*3*10^6 m/s*0.7T*sin (90)\\F=3.15*10^{-13}N

Thus, we can conclude that the Lorentz force acting on the proton will be 3.15×10^-13 N.

If the net force on an object is to the left, what will the direction of the resulting acceleration
Ivan

Acceleration points in the same direction as the net force, so to the left.

The direction of velocity can't be determined from this information alone, though. If the object is at rest, it will being moving to the left. If the object is already moving to the left, it will continue doing so and speed up. If it starts off moving to the right, it will continue to move to the right but eventually slow to a stop before starting to move to the left. There are more cases to consider if you're talking about motion in more than one dimension.

A water wave has a wavelength of 204 m and a frequency of 0.5 Hz. How far does it travel in 1 s?
Zigmanuir [339]

Answer:

c = 204 x 5 = 1020 m/s so it travels 1020 meters in 1 second.
