2 a) A water molecule is a good example of a molecule that exhibits a strong dipole moment. Given that water is an assymetric molecule with a hydrogen- oxygen- hydogen angle of about 105 degree. sketch the system and show the location of the resulting dipole moment. b) Given that the dipole moment of a measured magnitude of 6.2*10^-30 Cm. calculate the effective distance of the dipole moment if the effective charge seperation is 10 electron charges (the elctron...

To keep the calculations fairly simple, but still reasonable, we shall model a human leg that is 92.0 cm long (measured from the hip joint) by assuming that the upper leg and the lower leg (which includes the foot) have equal lengths and that each of them is uniform. For a 70.0 kg person, the mass of the upper leg would be 8.55 kg , while that of the lower leg (including the foot) would be 5.35 kg . Take...

The dipole moment of the water molecule (H2O) is 6.17×10−30 C.m. Consider a water molecule located at the origin whose dipole moment p? points in the +x-direction. A chlorine ion (Cl-), of charge −1.60 × 10−19 C, is located at x = 3 nm. Assume that x is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. (a) Find the magnitude...
