Answer:
Explanation:
magnification is the ratio of distance of image to distance of object
i.e.
As per the lens equation,
We will calculate the focal length of the mirror
Now for convex mirror only the sign will change
Thus, focal length would be equal to
Plugging this value into lens equation, we get
E1 = 2996.667N/C E2 = 11237.5N/C
E1 = kQ1/r^2
=8.99 x 10^9 x 30 x 10^-9/(30x10^-2)^2
= 2996.667N/C
E2 = kQ2/r^2
= 8.99 x 10^9 x 50 x 10^-9/(20x10^-2)^2
= 11237.5N/C
The direction are towards the point a
