h=3cm
F=-12cm
U=-18cm
Now, using Mirror formula
1\u +1/v = 1/f,
1/-18 +1/v =1/f
1/v=1/-12+ 1/18
1/v=-3+2/36
1/v=-1/36
V=-36
Now,
m=-v/u
m=-(-36)/-18
m=-2
Again,
m=h'\h
-2=h'/3
-2×3=h'
-6=h'
h'=-6
Therefore, distance of the image from the mirror is 36cm.
Height of the image is 6cm.

Now, Answer= -36/-6.
Therefore, option (b) is correct Answer. ❤❤❤❤
Please one like for it ❤❤❤

[shivam__chauhan]

Boards ki kasam jisne subscribe nhi Kiya wo exam me Fail 😂😂 (Meri jaban kaali hai) 💀☠️

[E-study-bz]

Targeted class- 10th...
Real class- no need to tell... 😂😂

[cutenext]

Plzzz bhaiya 🤌🥺Very urgent need for
class 9th ch tissue
And ch force and laws of motion 🔥
Exam is after 3 days

[commonthings]

Vote for Urgent need for class 9th –---
Biology ch 2 - tissues
Physics ch- Force and laws of motion 🔥🤌
Next week is my exam ... Plz ASAP🥲

[Aarambhop]

Please bring rapid revesion of
Acid base and salts 😢
Control and coordination 😮

[SKRYCREATE]

Given
h=3cm
F=-12cm
u=-18cm
Now using mirror formula
1/f=1/v+1/u
Rearrange
1/v=1/u+1/f
1/v=1/-18+1/-12
1/v=-6/216
V=-36
Now
M=-v/u
M=-36/-18
M=2
Now use
M=h'/h
2=h'/3
h'=6
:• (1) distance of the image from the mirror is -36
(2) Height of the image is = 6
:• option d is correct

[smratigupta]

Jo subscribe krega uske 98% + aayege (don't take risk ☠️)

[ummat-e-rasool_records]

26:40 the correct answer is b) -36, -6❤
