take a plastic straw and cut it into nearly two equal pieces suspend one of the pieces from the edge of a table with the help of a piece of thread now hold the other piece of straw in your hand and rub it's free and with the sheet of paper bring the rubbed end of the straw near the suspended straw. make sure that the two pieces do not touch each other. what do you observe? next rub the free end of the suspended piece of straw with a sheet of paper. again bring the piece of straw that was rubbed earlier with paper near the free end of the suspended straw what do you observe.. ( this is activity 11.7 please explain it..) please

Answer:
the straw gets attracted towards the other straw coz it gets charged when it is rubbed on a piece of paper.the type of force is electrostatic force
Explanation:
Take a plastic straw and cut it into nearly two equal pieces. Suspend one of the pieces from the edge of a table with the help of a piece of thread. Now hold the other piece of straw in your hand and rub its free end with a sheet of paper. Bring the rubbed end of the straw near the suspended straw. Make sure that the two pieces do not touch each other. Next, rub the free end of the suspended piece of straw with a sheet of paper. Again, bring the piece of straw that was rubbed earlier with paper near the free end of the suspended straw.
A straw is said to have acquired electrostatic charge after it has been rubbed with a sheet of paper. Such a straw is an example of a charged body.
The force exerted by a charged body on another charged or uncharged body is known as electrostatic force. This force comes into play even when the bodies are not in contact. The electrostatic force, therefore, is another example of a non-contact force.
Answer:
A straw rubbed with paper attracts another straw but repels it if it has also been rubbed with a sheet of paper.The force exerted by a charged body on another charged or uncharged body is known as electrostatic force.
