Answer:
B). to the right
Explanation:
Since the direction of magnetic field is into the page
So here we know that

now the velocity is from bottom to top
so we have

now the force on the moving charge is given as

now we have


so force will be towards Right
Answer:
centripetal acceleration of the ball is 6.9 m/s/s
tangential speed of the ball is 2.2 m/s
Explanation:
As we know that ball complete 5 rotations in 10 seconds
so frequency of rotation of ball is given as

now we know that angular frequency is given as



Now centripetal acceleration is given as



now the velocity of the ball at this angular frequency is given as



Answer:
A. cause i just took the test
Explanation:
I believe that the price will rise.
Hope this helps!
