What would happen to the planets in the solar system if the sun’s gravitational force were to suddenly disappear?

|
They will fly away in straight lines.
|

They will start moving toward the Sun

Explanation:
Detailed explanation-1: -If suddenly the Sun vanishes, the gravitational force between the Sun and the Earth will disappear. So, the Earth will no more be able to orbit around the sun. Thus, it will start moving in the direction of velocity in a straight line.
Detailed explanation-2: -Scientists estimate that the Sun will die in around 5 billion years. If the Sun miraculously disappeared, the Earth (and all the other objects in the Solar System) would continue their forward motion in a straight line off into space, instead of following their almost-circular orbits.
