Expert Solution & Answer
Explanation of Solution
Introduction:
Force due to gravity affectsevery object on the earth. According to Newton’s law of gravity, ‘every massive object exerts force of attraction on the other object’. The magnitude of the force is directly proportional to the product of the masses and inversely to the square of the distance between the object. Till 1915,it wasassumed that only a massive body is affected by the gravity. But after the
According to Einstein’s general theory of relativity, light can be affected by the strong gravity. In black hole, strong gravitational field at the center of the black hole bends the light inward. Depending on the of refractive index of the medium, when light passes from one medium to another medium, its speed changes. As the effect of gravitational field on the surface of the earth is negligible. Redshift is prominently observed in case of black hole. Redshift is observed in the electromagnetic radiation when light undergoes increase in wavelength. In case of frequency; during red shift, frequency decreases. The intense gravitational field just outside the black hole makes more effect on redshift. According to theory of relativity, when light goes downhill in the gravitational field, it decreases the frequency of light. The amount of redshift depends on the intensity of the gravity. Redshift observed in case of black hole; not in case of earth’s gravitational field.
Conclusion:
Therefore, frequency of light decreases, when moving downhill in the gravitational field. But in case of earth’s gravitational field, redshift is not observed. Bending of light isobserved in case of blackhole where gravity is very high that makes spacetime curvature.

- When current is flowing through the coil, the direction of the torque can be thought of in two ways. Either as the result of the forces on current carrying wires, or as a magnetic dipole moment trying to line up with an external field (e.g. like a compass). Note: the magnetic moment of a coil points in the direction of the coil's magnetic field at the center of the coil. d) Forces: We can consider the left-most piece of the loop (labeled ○) as a short segment of straight wire carrying current directly out of the page at us. Similarly, we can consider the right-most piece of the loop (labeled ) as a short segment straight wire carrying current directly into the page, away from us. Add to the picture below the two forces due to the external magnetic field acting on these two segments. Then describe how these two forces give a torque and determine if the torque acts to rotate the loop clockwise or counterclockwise according to this picture?
