The power of the lens combination =P1+P2=3-5=-2D The focal length of lens=1/p = -100/2=-50 cm We know the lens formula,1/f=1/v-1/u now u=-50 cm -1/50=1/v+1/150 Now solve it.... After you will get -25 as v. Therefore,position of image is 25 cm from the
Thank you so much Writeacher!!!!:)
Can you please help me fast..I am waiting for this question for several hrs..
