CUET Level II JEE Mock test 8 (Physics)

The force between two points charges placed in vacuum at distance 1 mm is 18 n if a glass is plate of thickness 1mm and dielectric constant 6 be kept between the charges then new force between them would be

• 18N

• 108N

• 3×10^-6N

• 3N

To similar and equal charges repel each other with force of 1.6 in when please 3M apart strength of each charge is

• 49 uc

• 20uc

• 4uc

• 2uc

Due to the motion of a charge its magnitude

• Does not change

• Increases are decreases depends on its speed

• Cannot be predicted

The coulomb electrostatic force is defined for

• Two spherical charges at rest

• Two spherical charges in motion

• Two point charges in motion

• Two point charges at rest

The electrostatic force between two charges Q1 and Q2 to at separation of is given by F = k. Q1 Q2 /r2

• Depends on the System of units only

• Depends on the the medium between the charges only

• Depends on both the both the medium between the charges under the System of units

• Is independent of both the System of units and the medium between the charges

When charges is given to a body

• More charge accumulate at region of small curvature

• More charge accumulate at region of large curvature

• Charges distributed Uni family irrespective of curvature

• None of the the above is true

Induction preceeds

attraction because

• An uncharged Body Body Can attract and uncharged body due to induction of opposite charge on it

• Charged body Can attract Can attract an uncharted body due to induction of same charge on it

• Charged body Can attract and uncharged body due to induction of opposite charge on it

• I charged can I track can I track another charged body due to induction of same charge on it

Identify the wrong statement in the following coulamb's law correctly describe the electric force that

• Binds the electrons of an atom to its nucleus

• Binds the protons burns the protons and neutrons in the nucleus of an atoms

• Binds autumns together to form molecules molecule

• Binds autumns and moleculars together to form solids

A neutral conducting rod is moving towards ya passitively charged conducting sphere as shown here what are the charges on the road and the spar when the rod is placed near the sphere

• Neutral positive

• Negative neutral

• Negative positive

• Positive positive
