Question 1 :
If three moles of monatomic gas is mixed with 1 moles diatomic gas, the resultant value of <em>γ</em>for the mixture is
Question 2 :
Two infinitely long parallel conducting plates having surface charge densities +<font face="Symbol">Σ</font> and –<font face="Symbol">Σ</font> respectively, are separated by a small distance. The medium between the plates is vacuum. If ε<sub>0</sub> is the dielectric permittivity of vacuum, then the electric field in the region between the plates is
Question 4 :
A capacitor of capacitance 4 <font face="Symbol">µ</font>F is charged to 80 V and another capacitor of capacitance 6 <font face="Symbol">µ</font>F is charged to 30 V. When they are connected together, the energy lost by the 4 <font face="Symbol">µ</font>F capacitor is
Question 5 :
A charge <em>q</em> is placed at a distance <em>a</em>/2 above the centre of a horizontal square surface of edge <em>a</em> as shown in figure. The electric flux through the square surface is <br> <img style='object-fit:contain' style="max-width:240px;" src="https://storage.googleapis.com/teachmint/question_assets/JEE%20Main/5f16c2ed1da6d070c2abf995"/>
Question 6 :
Capacitance of a capacitor made by a thin metal foil is $2\mu F$. If the foil is folded with paper of thickness 0.15 mm, dielectric constant of paper is 2.5 and width of paper is 400 mm, the length of foil will be
