Answer:
it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.
Explanation:
Magnetic field is along z axis while velocity is in x-z plane
so we will have
so here we can say
so we will have
so here the net force on the charge is perpendicular to its x directional velocity along - Y direction
So due to this component of motion it will move along a circle while other component of the motion will remain uniform always
So here it is combination of two parts
1) Uniform circular motion
2) Uniform motion
So we can say that it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.
Answer:
The magnitude of the boat's velocity is 8.21 km/h.
Explanation:
We can find the boat's velocity as follows:
Where:
and are the components of the velocity of the water in the x and y-direction
and are the components of the velocity of the boat in the x and y-direction
Since the angle is 15° we have:
Now, the velocity of the boat is:
Therefore, the magnitude of the boat's velocity is 8.21 km/h.
I hope it helps you!
It was <em>(1/2) (Net force on the cart) m/s²) </em>.
Answer:
v=3.649 m/s
Explanation:
Lets start with the force of gravity on the elevator.
But the friction clamp opposes this with a force of 17000 N
So the Net force on the elevator is
Kinetic Energy
The motion will be describe
original Kinetic energy + work done = final kinetic energy + spring energy
Answer:
Final velocity is the velocity which the body has at the end of the given time period.
