The convex spherical mirror is the diverging mirror. The image distance is 20.4 cm. The magnification is 0.417. The image is virtual and upright.
<h3>What is magnification?</h3>Magnification is the ratio of image distance to the object distance.
Object distance is 49 cm and the focal length of convex mirror is 35 cm, then image distance is calculated by the lens maker formula.
1/f = 1/v +1/u
1/-35 = 1`/v +1/49
v= -20.4 cm
Thus, the image distance is 20.4 cm.
The magnification is given by
m = v/u
m = -20.4 / 49
m = 0.417
Thus, the magnification is 0.417.
The image formed is by virtual meeting of light rays and above the principle axis. Thus the image is virtual and upright.

Answer:
The angle the wire make with respect to the magnetic field is 30°
Explanation:
It is given that,
Length of straight wire, L = 0.6 m
Current carrying by the wire, I = 2 A
Magnetic field, B = 0.3 T
Force experienced by the wire, F = 0.18 N
Let θ be the angle the wire make with respect to the magnetic field. Magnetic force is given by :
So, the angle the wire make with respect to the magnetic field is 30°. Hence, this is the required solution.
