nd the dimensions of (i) Power, (ii) Force and) Permittivity of vacuum (Eo).[Ans : (i) [L-MT(ii) ILMT 21 |
|
Answer» i) Power = Work / Time Work = Force * Distance Force = Mass * Acceleration Acceleration = Change in velocity /Time Velocity Dimension Formula = M^0 L^1 T^-1 Time Dimension Formula = T so Acceleration = M^0 L^1 T^-1 / T = M^0 L^ 1 T^-2 Force = M* M^0 L^ 1 T^-2 = M^1 L^1 T^-2 Work = M^1 L^1 T^-2 * L = M^1 L^2 T^ -2 Now Power = M^1 L^2 T^-2 / T =M^ 1 L^ 2 T ^ -3 |
