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 P pointing along positive along y – direction , then 0 ) with dipole moment P pointing along positive along y - direction The [...]

One end of a 2.4 m string is held fixed and the other end is attached to a weightless ring that can slide along a frictionless rod as shown in figure. The three longest possible wavelength One end of a 2.4 m string is held fixed and the other end is attached to a weightless [...]
