Answer 1

power of the lenses are +3 D and -5 D

combined power of both lenses

P(net)=P1+P2

P=3-5

P=-2 D

focal length of combination will be

P=1/f

f=1/P

f=-1/2

f=-0.5 meteres

f=-50 cm

since focal length is in -ve the combination behaves as a concave lens

1/f=1/v-1/u  (lens formula)

-1/50=1/v-(-1/50)

-1/50=1/v+1/50

1/v=-1/25

v=-25 cm

hence image is formed at 25 cm on the same side as that of the object

hope this helps and u understand well

Answer 2

tum vishu or meri sari chats parlo mujhe koyi problem nhi hai. par real thing to sun lo.

Mujhe vishu ne propose kiya tha. pahle ma man bhi gayi thi. par kuch din bad mujhe laga ki thik nhi hai ye. isiliye mane use boli ki chor do mujhe. par usne bola ki wo mujhe nhi chor sakta. Isiliye usne mujhe bola ki ma uski best friend banu. to mane man liya. Par aj bhi Vishu mujhse utnahi payar karta hai jaise pahle karta tha. par ma nhi karti usse payar kiuki mujhe aisi relation accha nhi laga. Mujhe ye love ki bare me kuch nhi pata tha. bas vishu ko ha karne ki bad sab pata chala. Or tabhi mujhe samajh me ayi ki mujhe is umar me aisa nhi karna chaiye. Isiliye aj tak jo bhi mujhe propose kiya use hi mane reject kar dia.Or ab yehi sajh hai ki i don't love vishu. He is just my best friend. I hope u will understand.
