Explanation / Answer

The focal length of the camera = f = 86.8 mm = 86.8×10-3 m

Diameter of sun = 1.40×106 km = 1.40×109 m

Distance of sun from earth = 1.50×108 km = 1.50×1011 mm

Let the size of image i.e diameter of image be 'd'

The image will be formed at focus of the lens .

Hence. size of image = {(86.8×10-3)/(1.50×1011)}×(1.40×109) = 0.81×10-3 m = 0.81 mm
