Answer:
south
cross sectional area of the beam
Explanation:
v = Velocity of ions =
Number of ions per =
Charge density would be the product of number of ions per and the charge of electrons multiplied by 2 as they are doubly charged.
Current density is given by
The current density is
The direction of the current density is opposite to the movement of the charged particle. The particles are moving north so the direction of current density will be to the south.
Current is given by
where A is the cross sectional area of the beam .
So the cross sectional area of the beam is required to determine the total current in this ion beam.

Answer:
Explanation:
= Initial momentum of the pin = 13 kg m/s
= Initial momentum of the ball = 18 kg m/s
= Momentum of the ball after hit
= Angle ball makes with the horizontal after hitting the pin
= Angle the pin makes with the horizotal after getting hit by the ball
Momentum in the x direction
Momentum in the y direction
The pin's resultant velocity is
The pin's resultant direction is below the horizontal or to the right.
Is there more info or is that just the question
