    The reading of a spring balance corresponds to 100 N while situated at the north pole and a body is kept on it. The weight record on the same scale if it is shifted to the equator, is \[\text{A=II,B=III}\]and radius of the earth, \[{{[Fe{{({{H}_{2}}O)}_{5}}NO]}^{2+}}\]

    A) 99.66 N     

    B) 110N

    C) 97.66 N                

    D) 106N

    Correct Answer: A

    Solution :

    At the pole, the weight is same as the true one Thus.\[40\mu A\] \[50\mu A\]                       \[114\mu A\] At the equator, the apparent weight is given by \[{{l}_{1}}\] Also the angular speed of an equatorial point on the earth's surface is \[{{T}_{1}}\] \[{{l}_{2}}\] Now \[{{T}_{2}}\] \[\frac{{{l}_{1}}+{{l}_{2}}}{2}\]
