Inflate two balloons. Hang them in such a way that they do not touch each other. Rub both balloons with woollen cloth and release them. Then:

  1. both balloons attract each other.

  2. both balloons repel each other.

  3. both balloons remain at same position.

  4. none of the above happens.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The balloons will be seen to repel each other as both are charged with same polarity.

When a person combs his hair static electricity is sometimes generated by:

  1. friction between comb and hair resulting in flow of electrons.

  2. induction between comb and hair.

  3. conducting property of hair.

  4. contact between comb and hair resulting in a charge.

A Correct answer
Explanation

Static electricity, while combing dry hair, is generated by friction between comb and dry hair.

Rub a glass tumbler with wool. Bring an inflated charged balloon, rubbed with wool, near refill. Then

  1. both balloon and tumbler will repel each other.

  2. both balloon and tumbler attract each other.

  3. no reaction will be observed.

  4. the balloon will burst.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

When rubbed by wool, glass becomes positive and rubber becomes negative. Opposite charges attract. So, the balloon and the glass tumbler will attract each other.

What happens when the end of the paper clip of electroscope is touched by hands?

  1. Electric current is produced 

  2. Foil strips remain as it is

  3. Foil strips collapse

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Because the charges on foil strips gets discharge through air body as soon as paper clip of electroscope is touched by hand, the foil strips collapse.

Opening up of strips of an electroscope is an indication of:

  1. proximity of a conductor.

  2. proximity of a charged body.

  3. proximity of an uncharged body.

  4. earth connection.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

When a charged body comes close to an electroscope, charges are induced to the electroscope. These charges flow down to the metal strips which open up due to repulsion for having similar charges.
