364543 A small telescope has an objective lens of focal length \(140\;cm\) and eye piece of focal length \(5.0\;cm\). The telescope is used to view a \(100\;m\) tall tower \(3\;km\) away. The height of the image of the tower formed by objective lens is

364544 An astronomical telescope with magnification 50 is to be designed in normal adjustment. Length of the tube is \(102\;cm\). The powers of objective and eyepiece are respectively.

364545 An astronomical telescope has objective and eyepiece lens of powers \(0.5\;D\) and \(20\;D\) respectively, its magnifying power will be

364546 A giant telescope in an observatory has objective of focal length \(19\;cm\) and an eyepiece of focal length \(1.0\;cm\). In normal adjustment, the telescope is used to view the moon. Diameter of image of the moon formed by the objective is (The diameter of the moon is \(3.5 \times {10^6}m\)and the radius of the lunar orbit round the earth is \(3.8 \times {10^8}m\) )
