A particle moves towards a concave mirror of focal length `30cm` along its axis and with a constant speed of `4cm//sec`. At the instant the particle is `90cm` from the pole

A particle moves towards a concave mirror of focal length 30 cm along its axis and with a constant speed of 4 cm/ sec. What is the speed of its image when the particle is at 90 cm from the mirror?

A particle moves toward a concave mirror of focal length 30 cm along its axis and with a constant speed of (4 cm)/(s) . What is the speed of its image when the particle is at 90 cm from the mirror?

A point object on the principal axis of a concave mirror of focal length 20 cm, is moving at a speed of 5 cm/s at an single 45^(@) to the principal axis as shown of 25 cm from the pole of mirror.Find the velocity components of image along and normal to principal axis at this instant

If an object is 30 cm away from a concave mirror of focal length 15 cm the image will be

An object is moving towards a concave mirror of focal length 24 cm. When it is at a distance of 60 cm from the mirror, its speed is 9 cm//s . The speed of its image at that instant , is

A concave mirror and a convex mirror of focal lengths 10cm and 15cm are places at a distance of 70cm. An object AB of height 2cm is places at a distance of 30cm from the concave mirror. First ray is incident on the concave mirror then on the convex mirror. Find size, position, and nature of the image.
