When an object is kept at a distance of 30 cm from a concave mirror, the image is formed at a distance of 10 cm. If the object is moved with a speed of 9 m/s, the speed with which image moves is

Options:

Answer:

Solution:

m = - \frac{v}{u} = - \frac{10}{30} = - \frac{1}{3}

V_{I} = - m^{2} V_{O} = - (\frac{1}{3})^{2} \times 9 = - 1 m/s

Speed of image = 1 m/s
