Question

1. An object is placed at a distance of 15 cm in front of a convex mirror of focal length
10 stol image is formed at a distance of
a) sembles than 15 cm d more than 15 cm. d) infinity ​

Answer 1

u= -15 cm , f= 10 cm, v=? using lens formula

1/f=1/v-1/u , 1/10=1/v-(-1/15) , 1/10-1/15=1/v , 1/v= 15-10/150 , 1/v = 5/150 then v is 30cm image form by lens is more than 15 cm
