then the torque exerted by the field on the dipole is


Now to rotate the dipole in the field to its final position the work required to be done is




Minimum energy mB is for the case when m is anti parallel to B.

Answer:
Distance between centre of Earth and centre of Moon is 3.85 x 10⁸ m
Explanation:
The attractive force experienced by two mass objects is known as Gravitational force.
The gravitational force is determine by the relation:
....(1)
According to the problem,
Mass of Moon, m₁ = 7.35 x 10²² kg
Mass of Earth, m₂ = 5.97 x 10²⁴ kg
Gravitational force experienced by them, F = 1.98 x 10²⁰ N
Universal gravitational constant, G = 6.67 x 10⁻¹¹ Nm²kg⁻²
Substitute these values in equation (1).



d = 3.85 x 10⁸ m
Mars is 139.58 million miles away from the sun. mars is red because its soil has iron oxide (rust particles) in it.
