Question

True & False Statement Type
$S_1$ : At extremely high temperature, degree of freedom of monatomic gas become 5 due to activation of vibrational degree of freedom.
$S_2$ : For a uniformly charged solid non-conducting sphere potential is maximum at it's centre.
$S_3$ : Breaking stress of wire depends on its cross-sectional Area.
$S_4$ : Only time varying magnetic field produces induced electric field which have closed lines of force.

• A. FFFT
• B. TTTF
• C. FTFT
• D. TFTF

Answer 1

Answer: (C)

FTFT

No degree of freedom adds up to the three translational degree of freedom of monoatomic gas due to achievement of high temperature. Hence statement 1 is false.

Maximum work would be done in bringing a charge from outside to the center of a non conducting charged sphere. Hence potential is maximum at that point.

Breaking stress is a property of material of the wire, and does not depend on cross sectional area explicitly. Hence statement 3 is false.

Only time varying magnetic field produces induced electric field which have closed lines of force.
