what is the magnification of an image when using a 10 inch diameter telescope with a focal length of 1000 mm when using an eyepiece with a 35 mm focal length?

Given the diameter of the telescope = 10 inchesThe focal length of the telescope = 1000 mmThe focal length of the eyepiece = 35 mmThe formula to find the magnification isMagnification = Focal length of telescope / Focal length of the eyepiece= (1000 mm)/(35 mm)=  40x.Magnification The amount a telescope magnifies an object. It is the focal length of the telescope divided by the focal length of the eyepiece. As a rule of thumb, the maximum usable magnification of a telescope is 50 times the aperture or 2 times the aperture. For example, a handheld lens may be labeled 10x. This means that the lens magnifies the object ten times its actual size. Compound microscopes use two or more lenses to magnify a sample.Learn more about Magnification here:-https://brainly.com/question/15744335#SPJ4
