    C)  3 represents far-sightedness

    D)  4 correction for far-sightedness

    Correct Answer: A

    Solution :

    Here, \[E=1500\,V/m,\,B=0.4\,Wb/{{m}^{2}}\] Minimum speed of electron along the straight line \[\upsilon =\frac{E}{B}\]                                 \[=\frac{15000}{0.4}\]                                 \[=3750\]                                 \[=3.75\times {{10}^{3}}m/s\]
