Question

if an object of 10cm is placed at a distance of 36 centimetres from a concave mirror of focal length 12 centimetre find the position, nature and height of the mirror

Answer 1

*********************ANSWER*************************

=========================================

GIVEN :

ho=10cm

u=-36cm

f= -12cm

hi=?

SOLUTION:

1/f = 1/v + 1/u

1/-12 = 1/v + 1/-36

1/36 + 1/-12 = 1/v

(Lcm 36&12=36)

1-3/36 = 1/v

1/v= -18

v= -18

m=hi/ho = -v/u

 = hi= -v.ho/u

       = -(-18) 10/ 36

       = 180/36

    hi = 5cm
