FAQs on NCERT Solutions for Class 8 Science Chapter 11 - In Hindi
1. A rocket has been fired upwards to launch a satellite in its orbit. Name the two forces acting on the rocket immediately after leaving the launching pad?
Gravitational force and frictional force are the two forces operating on the rocket as soon as it leaves the launch pad. The gravitational force is directed downwards towards the earth, whereas the frictional force is directed upwards owing to the surrounding air. These forces have to be combated to make the rocket launch into the sky.

2. An inflated balloon was pressed against a wall after it has been rubbed with a piece of synthetic cloth. It was found that the balloon sticks to the wall. What force might be responsible for the attraction between the balloon and the wall?
When an inflated balloon is pressed against a wall after it has been rubbed with a piece of synthetic cloth, the balloon sticks to the wall due to an attraction between the balloon and the wall. The attraction between the ball and the wall is due to an electrostatic force. When we rub the balloon with a synthetic cloth, it becomes charged, and when we bring it close to the wall, the electrostatic force attracts it to the uncharged wall.
3. How to calculate the total force?
Forces acting in the same direction on an item add to one another. When two forces operate on an item in opposing directions, the net force exerted on it is equal to the difference between the two forces. A force might be stronger or weaker than the other, or they could be equal. The magnitude of a force is commonly used to describe its strength. We must additionally indicate the force's direction of action. Also, if the applied force's direction or magnitude varies, the impact changes as well.
4. How to score full marks in the Class 8 Science exam apart from thoroughly studying Chapter 11?
Your Class 8 Science grade will be heavily influenced by how well you study and write tests. To get high grades, you should go over the whole syllabus and practise a variety of questions to ensure that you understand all of the ideas covered in class. Also, make sure you're writing properly and neatly. On your answer sheet, draw all of the diagrams using a pencil and underline all of the keywords.
