Question

an object is placed at the distance of 25 m from a concave mirror of the length of 10 cm find the nature and position of the image so formed

Answer 1

here the obj. is placed beyond c. so the img will be real and inverted.                           1/v_1/u= 1/f .by solving it by taking u =_2500cm and f= _5 cm we will get v as approx _6 cm
