[C] 8 cm Magnification, m = 3 v = 24 cm, Image distance Object distance, u =? As, m = v/u u = v/m =24/3 = 8 cm Hence, she should put the object at 8 cm from the lens L₂.
[C] 8 cm
Magnification, m = 3
v = 24 cm, Image distance
Object distance, u =?
As, m = v/u
u = v/m
=24/3
= 8 cm
Hence, she should put the object at 8 cm from the lens L₂.
[C] Sour and change Blue litmus to Red You must know that acid turns blue Litmus solution to red. They have a sour taste as in the case of vinegar and are sticky to touch. Hence, your answer will be option [C].
[C] Sour and change Blue litmus to Red
You must know that acid turns blue Litmus solution to red. They have a sour taste as in the case of vinegar and are sticky to touch. Hence, your answer will be option [C].
(C) Remain at the same position When a nail is inserted in the trunk of a tree at a height of 1 metre from the ground, even after 3 years the nail remains at same level.
(C) Remain at the same position
When a nail is inserted in the trunk of a tree at a height of 1 metre from the ground, even after 3 years the nail remains at same level.
Saraswati did some preliminary experiment with the lenses and found out that the magnification of the eyepiece (L₂) is 3. If in her experiment with L₂ she found an image at 24 cm from the lens, at what distance did she put the object?
[C] 8 cm Magnification, m = 3 v = 24 cm, Image distance Object distance, u =? As, m = v/u u = v/m =24/3 = 8 cm Hence, she should put the object at 8 cm from the lens L₂.
[C] 8 cm
See lessMagnification, m = 3
v = 24 cm, Image distance
Object distance, u =?
As, m = v/u
u = v/m
=24/3
= 8 cm
Hence, she should put the object at 8 cm from the lens L₂.
