A) zero
B) infinite
C) one
D) information insufficient
Correct Answer: A
Solution :
In taking charge from P to 0, one has to perform work against the force experienced by charge due to the induced electric field. The induced electric field is perpendicular to line POQ and hence \[{{W}_{1}}=0\], while to compute exact value of \[{{W}_{2}}\] various distances and variations of magnetic field with time must be known, but it can be predicted that \[{{W}_{2}}\] is non-zero. So, ratio \[\frac{{{W}_{1}}}{{{W}_{2}}}=0\].You need to login to perform this action.
