Practicing Success
If the dimensions of length are expressed as $G^xc^yh^z$; where G, c and h are the universal gravitational constant, speed of light and Planck’s constant respectively, then |
a, b c, d b, d a, c, d |
b, d |
The correct answer is Option (3) → b, d lenght $l = G^x\, c^y\, h^z$ or $M^0LT^0 = [M^{–1}L^3T^{–2}]^x [LT^{–1}]^y [ML^2T^{–1}]^z$ After comparing, we get $x = 1/2, y = –3/2, z = 1/2$ |
