8x + 4 = 3 (x – 1) +
8x + 4 = 3 (x – 1) +
`3 (5x – 7) + 2(9x – 11) = 4(8x – 7) –
The arrangement shown consists of three elements. (i) A thin rod of charge `–3.0 muC` that forms a full circle of radius 6.0 cm. (ii) A second thin rod of charge `2.0 muC` that forms a circular arc of radius 4.0 cm and concentric with the full circle, subtending an angle of 90° at the centre of the full circle. (iii) An electric dipole with a dipole moment that is perpendicular to a radial line and has magnitude `1.28 × 10^(–21)C-m.` Find the net electric potential in volts at the
The electric potential in a region is given by the relation `V(x) = 4 + 5x^2` . If a dipole is placed at position (–1,0) with dipole moment `vecp` pointing along positive Y-direction,
