an object placed at distance of 4 centimetres in front of a convex mirror whose focal length is 5 centimetres.where is image formed |
| Answer» OBJECT Distance (u) = 4 cm (negative) focal length of the lens (F) = 5 cm we know, convex mirror ALWAYS forms the virtual, upright and diminished. Also, object distance in the convex mirror os always negative where as image distance and focal length are positive. Now, Applying the mirror's formula, 1/f = 1/v + 1/u 1/5 = 1/v +1 1/5 = (4-v) /4V 4v = 5(4-v) 4v = 20-5v 9v = 20 v = 20/9 = 2.222 _______________________________________________Hope it helps If helped mark me as the BRAINLIEST_________________________________________________- | |
