Electric charges \(+q\) and \(-q\) are placed at points \(A\) and \(B\) respectively which are at a distance of \(2 L\) apart. If \(C\) is the midpoint between \(A\) and \(B\), then the work done in moving a charge \(+Q\) along the semi-circle \(C R D\) is
- A \(\frac{q Q}{2 \pi \varepsilon_0 L}\)
- B \(\frac{q Q}{6 \pi \varepsilon_0 L}\)
- C \(-\frac{q Q}{6 \pi \varepsilon_0 L}\)
- D \(\frac{q Q}{4 \pi \varepsilon_0 L}\)

- A conducting rod of length \(L\) lies in \(X Y\)-plane and makes an angle \(30^{\circ}\) with \(X\)-axis. One end of the rod lies at origin initially. A magnetic field also exists in the region pointing along positive \(Z\)-direction. The magnitude of the magnetic field varies with \(y\) as \(B_0\left(\frac{y}{L}\right)^3\), where, \(B_0\) is a constant. At some instant the rod starts moving with a velocity \(v_0\) along \(X\)-axis. The emf induced in the rod isTS EAMCET 2018 Hard
