Question

Chapter 34, Problem 1OQ

(i)

To determine

The net force exerted on the grain.

(i)

Expert Solution

Answer to Problem 1OQ

Option (c) zero.

Explanation of Solution

According to the inverse square law of Newton, the force of gravity acting between any two objects are inversely proportional to the square of the separation between the object's centers. The light intensity pressure will also follow the inverse square law of Newton.

If the grain is moved to a distance 2r1 from the Sun, both the gravity force and intensity pressure on the grain will decrease, so the net force on the grain will be zero.

Conclusion:

Both the gravity force and intensity pressure on the grain will decrease so the net force on the grain will be zero. Therefore, option (c) is correct.

Both the gravity force and intensity pressure on the grain will decrease so the net force on the grain will be zero. Since it is given as net force is towards the sun. Therefore, option (a) is incorrect.

Both the gravity force and intensity pressure on the grain will decrease so the net force on the grain will be zero. Since it is given as net force is away from the Sun. Therefore, option (b) is incorrect.

Both the gravity force and intensity pressure on the grain will decrease so the net force on the grain will be zero. Since it is given that it is not possible to determine the net force without the mass of the grain. Therefore, option (d) is incorrect.

(ii)

Answer to Problem 1OQ

Option (a) toward the Sun.

Explanation of Solution
