1.) The formula for magnetic force is F = qvBsinθ.
Substituting, we have F=(5.0 × 10^–7 C) (2.6 × 10^5 m/s) (1.8 × 10^–2 T)(sin90°) [90° because point charge is perpendicular to magnetic field]
F = 2.34 x 10^-3 N
Answer is B.
2.) <span>The distance is reduced by 1/2, so B is twice or 0.2 T. Answer is D.</span>
Answer: a steel. Plate
Explanation: just did it on apex
Convex mirrors can only produce virtual images because the focal point and the center of curvature of the convex mirror are imaginary points and that cannot be reached.
<h3>What is virtual image?</h3>
This is referred to the opposite of a real image and cannot be obtained on a screen. It is formed from the apparent divergent of light rays from a point and not the actual one which is the major difference it has with a real image.
It is usually produced by a convex mirror because the focal point and the center of curvature of the convex mirror are imaginary points which can't be reached.

Answer:
The distance is 
Explanation:
From the question we are told that
The smallest shift is 
Generally a grid unit is 
of an arcsec
This implies that 0.2 grid unit is 
The maximum distance at which a star can be located and still have a measurable parallax is mathematically represented as
substituting values
Note 
So
