A concave mirror of radius of curvature 20cm has a pin placed at 15cm from its pole. What will be the magnification of the image formed?
A
4.00
B
2.00
C
1.33
D
1.50
E
0.25
Verified Correct Answer: B.
Physical Principles & Numerical Solution
1/U + 1/V = 1/f
f = r/2 = 10cm; 1/15 + 1/v = 1/10
v = 30 = m = v/u = 2
