How far should an object be placed from the pole of a concave mirror of focal length 20cm to form a real image whose size is one fifth of the size of the object?

Answer: The object should be placed at a distance of 100 cm from the pole of concave mirror.

At what distance from a concave mirror of focal length 10 cm should an object be placed so that?

The object should be placed at a distance of 6.66 cm on the left side of the mirror.

When an object is placed at a distance of 50 cm from a concave mirror the magnification produced is where should the object be placed to get a magnification of 1 5?

Answer Expert Verified u = – 50 cm. So, the focal length of mirror is 60 cm. Therefore, required distance of the object to produce a magnification of -1/5 is 100 cm.

How far should an object be from the pole?

The object should be placed 100 cm to the left of the mirror.

How far should an object be placed from a convex lens?

An object should be placed at distance 60 cm from the convex lens.

Where should an object be placed from a concave mirror of focal length 10 cm so as to obtain a real image of magnification 2?

focal length , f = 10 cm. By the Mirror formula, On solving, Thus the object should be placed at 15 cm in front of mirror.

At what distance from a concave mirror of focal length 10cm should an object 2cm long be placed in order to get an erect image 6cm draw the ray diagram?

-6.7cm
So At -6.7cm distance from a concave mirror of focal length 10 cm should an object 2 cm long be placed in order to get an erect image 6 cm tall.

When an object is placed at a distance of 50cm from?

When an object is placed at a distance of 50 cm from a concave spherical mirror the magnification produced is – (1/2). When an object is placed at a distance of 50 cm from a concave spherical mirror, the magnification produced is .
