Answer:
0
Explanation:
Since momentum is given by:
Therefore momentum is a vector quantity in the direction of velocity.
<u>This case can be described mathematically as:</u>
since the mass and velocity are equal:
net momentum:
Answer:
Explanation:
From the question we are told that
Mass
Height
Generally the equation for velocity before impact is is is mathematically given by
Generally the equation for Kinetic Energy is is mathematically given by
Answer:
B = 7.6 T direction of + x
Explanation:
For the proton beam to continue in the same direction the electric and magnetic forces must be equal
= 0
= F_{e}
Fm = q E
The electric force is in the direction of the electric field because it is the charge of the positive proton, the electric force goes in the direction of –y, therefore, the magnetic force cancels this force must go in the direction of + y
The magnetic force is
F_{m} = q v x B = q v B sin θ
θ = 90
B = q E / q v
B = E / v
B = 800/105
B = 7.6 T
To find the direction of the magnetic field we use the right hand rule, the thumb goes in the direction of the proton velocity, the fingers extended in the direction of the magnetic field and the palm is the direction of force, for a positive charge.
Thumb goes in the direction of the + z axis
Palm in the direction of +y
Fingers point in the direction of + x
