MCQ (Single Correct Answer)

-1

Some physical quantities are given in Column I and some possible SI units in which these quantities may be expressed are given in Column II. Match the physical quantities in Column I with the units in Column II and indicate your answer by darkening appropriate bubbles in the 4 $$\times$$ 4 matrix given in the ORS.

	Column I		Column II
(A)	GM$$_e$$M$$_s$$ G - universal gravitational constant, M$$_e$$ - mass of the earth, M$$_s$$ - mass of the Sun	(P)	(volt) (coulomb) (metre)
(B)	$${{3RT} \over M}$$ R - universal gas constant, T - absolute temperature, M - molar mass	(Q)	(kilogram) (metre)$$^3$$ (second)$$^{-2}$$
(C)	$${{{F^2}} \over {{q^2}{B^2}}}$$ F - force, q - charge, B - magnetic field	(R)	(metre)$$^2$$ (second)$$^{-2}$$
(D)	$${{G{M_e}} \over {{R_e}}}$$ G - universal gravitational constant, M$$_e$$ - mass of the earth R$$_e$$ - radius of the earth	(S)	(farad) (volt)$$^2$$ (kg)$$^{-1}$$

(A)→(P), (Q); (B)→(R), (S); (C)→(R), (S); (D)→(R), (S)

(A)→(P); (B)→(R), (S); (C)→(R), (S); (D)→(R)

MCQ (Single Correct Answer)

A system of binary stars of masses $m_{\mathrm{A}}$ and $m_{\mathrm{B}}$ are moving in circular orbits of radii $r_{\mathrm{A}}$ and $r_R$, respectively. If $\mathrm{T}_A$ and $\mathrm{T}_B$ are the time periods of masses $m_A$ and $m_B$ respectively, then

$\frac{\mathrm{T}_{\mathrm{A}}}{\mathrm{T}_{\mathrm{B}}}=\left(\frac{r_{\mathrm{A}}}{r_{\mathrm{B}}}\right)^{\frac{3}{2}}$

$\mathrm{T}_{\mathrm{A}}>\mathrm{T}_{\mathrm{B}}$ if $\left(r_{\mathrm{A}}>r_{\mathrm{B}}\right)$

$\mathrm{T}_{\mathrm{A}}>\mathrm{T}_{\mathrm{B}}$ if $\left(m_{\mathrm{A}}>m_{\mathrm{B}}\right)$

$\mathrm{T}_{\mathrm{A}}=\mathrm{T}_{\mathrm{B}}$
