    A convex lens of focal length/is placed somewhere in between an object and a screen.The distance between object and screen is x.If numerical value of magnification producedby lens is m, focal length of lens is

    A) \[1.25\times {{10}^{6}}\]                             

    B) \[\frac{G}{19}\]

    C) \[\frac{G}{20}\]               

    D) \[E=16T-0.04{{T}^{2}}\mu V.\]

    Correct Answer: A

    Solution :

                    Here,   \[\left( \frac{0.4}{\pi } \right)\]                    ......(i) \[11.4\Omega ,15.5A\] and image is real, magnification is negative                 \[30.7\Omega ,6.5A\] From, - \[40.4\Omega ,5A\] \[50\Omega ,5A\] \[{{R}_{1}}\] Put in Eq. (i)                 \[{{R}_{2}}\]                 \[{{R}_{1}}>{{R}_{2}}\]
