वर्तिका अग्निहोत्री answered • 13 hours agoBy convex lens formula:1/v - 1/u =1/f
v = f*u/u-f ; 200*200*10³/200-200*10³ (2km=200*10³cm)
v= 200*10³/999
in magnification, {v/u} = {h'/h}
so, 200*10³/999*200*10³
h'=5000/999=5.005
h' is nearly equal to 5cm.
v = f*u/u-f ; 200*200*10³/200-200*10³ (2km=200*10³cm)

so, 200*10³/999*200*10³
h'=5000/999=5.005
