Force = G(1)(1)/(1000^2)=6.67×10^-17 N; if 1 eluoj (energy unit) = unit force × 1 m, then 1 eluoj = 6.67×10^-17 J.

Using B = F/(qv) with F dimension M L T^-2, q as Coulomb and v as L T^-1 gives B dimension M T^-1 C^-1, which is option C.

If v (velocity) = f × A (wavelength), then f is frequency with dimensions [T^{-1}].

The gravitational constant G has physical units (N·m^2·kg^-2), so it is dimensional; the others are dimensionless.

Dimensional analysis gives x=1 from time exponents, y=-1 from mass balance, and then z=-1 from length exponent, so (1, -1, -1).

The dimensional formula of G is M^-1 L^3 T^-2, consistent with Newton's law of gravitation.

Impulse has the same dimensions as momentum: mass × length × time^-1, written as M L T^-1.

R has dimension L^-1, so R h c has dimensions L^-1 × (M L^2 T^-1) × (L T^-1) = M L^2 T^-2, which are the dimensions of energy; thus option C is correct.

Weight, tension and buoyant force are forces (newtons), while electromotive force is potential difference (volts), different units.

Linear inertia refers to mass which has dimensional form ML^0T^0, so option C is correct.
