E Both A & C, need an explanation?
Answer:
C) Gravitational force
Explanation:
Steve is whirling a rubber cork, tied with a string to his finger, over his head as shown in the figure.
The motion of the cork is similar to the motion of a planet in the Solar System around the Sun.
Therefore Gravitational force is similar to the tension in the string. The reason is because the planets revolve around the sun due to the Gravitational force due to which they are pulled towards the sun and do not stray away.
A more positive mindset should lead to a more enjoyable life.
