Question

At what distance from a concave mirror an object shouldbe placed to get an imagr half th size of the object ?

Answer 1

Answer:

Explanation:

It is not possible as:

Angle/360°-1= 1/2

Then,angle-360/360=1/2,

So,angle-360=1/2×360(i.e.180)

Therefore,angle=180+360

Thus,angle=540°

But, there can be only 360°.
