A point object O moves from the principal axis of a converging lens in a direction OP. I is the image of O, will move initially in the direction

Text Solution

Verified by Experts

The correct Answer is:
C

(i) `v_(Ix) = m^(2)v_(0x)` (same direction)
(ii) `because` m = -ve , `m=(v)/(u)`,
(v=-ve, u =+ve) then `v_(Iy)` = -ve
