Answer:
The magnitude of electromagnetic forces is greater than the magnitude of gravitational forces.
Explanation:
There are four fundamental forces in nature. These are as follows :
(1) Gravitational force
(2) Electromagnetic force
(3) Weak force
(4) Strong force
Gravitational force is the weakest force among all the fundamental forces. The gravitational force exists between masses present in the universe while the electromagnetic force exist between charged particles. The magnitude of gravitational force is weaker than the electromagnetic force. It is about times more than gravitational force.
Hence, the correct statement about forces in the solar system is (A).

Answer:
Explanation:
Given
Kinetic energy varies jointly as mass and square of velocity
for
for
Divide 1 & 2 we get
Kinetic energy is proportional to mass and the square of velocity. It can be calculated for different masses and velocities using a constant derived from specific known values.
The principle of kinetic energy states that kinetic energy is directly proportional to mass and the square of velocity. Therefore, we can use the equation Kinetic Energy = 0.5 * Mass * Velocity^2 to calculate kinetic energy.
In this example, a mass of 15 grams and a velocity of 3 cm/s generates a kinetic energy of 27 ergs. By this equation, we derive a constant K. For a mass of 5 grams and a velocity of 9 cm/s, we can easily find the kinetic energy using this K value and multiplying it with the given mass and the square of the velocity.
