q9We consider a dipole molecule in a region of space where there is aNON-uniform electrostatic field (electrostatic field exerted on thepositive charge of the dipole is different from that exerted on thenegative charge). The molecule will undergo:
a) rotation.b) a translation.c) a rotation and a translation.d) no movement.q11A heating element is immersed in water in a beaker. It is connectedto a fixed voltage source of 12 V. You want to increase theelectrical power of the heater.
What should be done ?
a) Lengthen the wire of the heating body (increase the length ofthe wire)
b) Shorten the wire of the heating body (reduce the length of thewire)
c) None of the above.
