@@satishalaj2391 nah, m=v/u 30/-15 =-2 A Real Inverted and Enlarged Image only also u can cross check that if u see the object is at 15 cm so it is b/w F1 and 2F1 therefore The image must form on the other side of lens being positive but enlarged!
mam in the 3rd question m=v/u as we are talking about lens and you have taken -v/u and for u you have substituted the value of f and the answer should be m=-2 and h of image should be -4
Mam one doubt in beginning you told magnification for convex lens or convex mirror is v/u but in third question you took magnification as -v/u please reply mam
Mam please start crash course to 24-25 bacth
In third question, finding magnification you have taken u=10 but given u=-15
check I had interchanged formula f= 10 u= -15
M=-v/u=-30/-15=2 this is correct in 3rd question
@@dvsmath i think this is wrong
@@dvsmath no mam... U =-15 and f=10 cm by this we get m =-2 and h' = -4

Thank you mam

Thank you so much mam deepa mam

please check
Mam how to find position formed..
Mam that homework question answer
V = +6
Position is behind the mirror
Nature is virtual and erect..
How to know behind the mirror...😢
Mam one doubt in beginning you told magnification for convex lens or convex mirror is v/u but in third question you took magnification as -v/u please reply mam
@shirazbanu7667 thank you

Mam 3 question answer of height of image is +4 cm
Mam in finding magnification you had take object distance u=-10 but u=-15 and f =+10 in third question
Virtual errect diminished
Mam 3 question in magnification you taken u= 10 in question they given -15
Miss in question 3 you have taken magnificent V=10 but it is -15
27:10
Miss you have mistaken in doing the magnification by taking positive sign in object distance
In physics 3 question magnification is -2
3rd questions
Please human eye numerical please mam.
Magnification formula for lens is m=v/u but you have taken m=-v/u in the third question so please observe😊

Hi
Bye miss
3rd question is wrong
Excuse me mam that m=2 but you have written that m=-3 🙄🙄
Observe the changes made while solving
