The answer to your question is option 1. I hope this has helped.
Answer:
Gravity or the gravitational force is defined as the force of attraction occurring between all states of matter. The sun’s gravity, mass, and radius plays a crucial role in the properties of the Sun.
Explanation:
The gravity of an object can be determined using the formula:

Now, according to the question, the mass of the sun is halved, which will be written as:

Thus, according to the equation, the mass of an object is directly proportional to the gravitational field. since, the mass of the Sun is reduced to half, the gravity of the Sun will be halved.
Answer:
An object has potential energy (stored energy) when it is not in motion. Once a force has been applied or it begins to move the potential energy changes to kinetic energy (energy of motion).
Therefore, true. (Also would u mind giving brainliest, you don't have to hehe)
