18feet
Explanation:
We need to find the distance,c between the vertex and the focus.
For a vertical parabola:
#If we place our parabola at the center, the expression changes to:
The points of the parabola are given as (12,2), substitute in our equation to find c:
Hence, the receiver should be placed at 18ft
Answer:
The magnitude of magnetic field is 1.19 T and its direction magnetic is in negative x direction.
Explanation:
Given that,
Speed of a proton, (due +x direction)
When it moves in the positive y direction it experiences a force of, (due positive z direction)
We need to find the magnitude and direction of the magnetic field. The magnetic force is given by :
For direction :
So, the magnitude of magnetic field is 1.19 T and its direction magnetic is in negative x direction.
