Explanation:
It is given that,
An electric dipole consists of charges +2e and -2e separated by 0.82 nm
Charge,
Distance between charges,
Electric field strength,
(a) The magnitude of the torque on the dipole is given by :
When dipole moment is parallel to the electric field,
(b) When the dipole is perpendicular to the electric field,
(Since, p = q × d)
(c) When the dipole moment is anti parallel to the electric field,
Since,
Hence, this is the required solution.
Answer:
where , F = Gravitational force
G = Gravitational constant
= mass of first object
= mass of second object
r = distance between the two objects
As Gravitational force is inversely related to the distance between two objects, lesser is the distance , more will be the gravitational force. As distance between C and D is more , the force shoulld have been less. That means the product of the masses of the objects C and D is more than the product of the masses of the objects A and B.
