A girl brings a positively charged rod near a thin neutral stream of water from a tap. She observes that the water stream bends towards her. Instead, if she brings a negatively charged rod near to the stream, it will
1 Bend in the same direction
2 Bend in the opposite direction
3 Not bend at all
4 Bend in the opposite direction above and below and rod
Explanation:
When a charged rod is brought nearer to stream of water, dipoles will be induced in the water (polar molecules). The dipoles will be always attracted by the charged rod. So stream bend in the same direction.

Assertion : If there exists coulombic attraction between two bodies both of them may not be charged. Reason : In coulombic attraction two bodies are oppositely charged.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Coulombic attraction can occur between a charged body and a neutral body or between two oppositely charged bodies. The reason is partially true but not complete. Coulombic attraction can indeed occur between oppositely charged bodies, but it can also occur between a charged body and a neutral body due to the influence of the charged body on the distribution of charges in the neutral body. So correct option is (3).

A positively charged rod is brought near an uncharged conductor. If the rod is then suddenly withdrawn, the charge left on the conductor will be
1 Positive
2 Negative
3 Zero
4 Cannot say
Explanation:
Positively charged rod includes negative charge on the side of the sphere closer to the rod and an equal positive charge on the side away from the rod. When the rod is withdrawn, the negative charges move to neutralise the equal positive charge. The charge left is zero.

Two identical metal spheres \(A\) and \(B\) are supported on insulating stands and placed in contact. What kind of charges will \(A\) and \(B\) develop when a negatively charged ebonite rod is brought near \(A\)?
1 \(A\) will have a positive charge and \(B\) will have a negative charge
2 \(A\) will have a negative charge and \(B\) will have a positive charge
3 Both \(A\) and \(B\) will have positive charges
4 Both \(A\) and \(B\) will have negative charges
Explanation:
In contact, \(A\) and \(B\) behave as one body. Therefore, by induction, positive charge developes on \(A\) and negative charge develops on farther side of \(B\).
