Find the dimensional formula of (a) coefficient of viscosity `eta` (b)charge `q` (c ) potention `V` (d) capacitance `C` and ( e) resistance `R` Some of the equations containing these quantities are `F= -etaA [[Delta v )/(Delta l]], q = It. U = VIt, q = CV and V = IR ` where A denotes Area, the v the velocity , I is the length ,I the electric current, t the time and U the energy .A. `[ML^(2)T^(-2)]`B. `[ML^(-1)T^(1)]`C. `[ML^(-2)T^(-2)]`D. `[M^(0)L^(0)T^(0)]` |

Answer» Correct Answer - b `F = - eta A(Delta v)/(Delta z) rArr [eta] = [ML^(-1)T^(-1)]` As `F = [MLT^(-2)] A = [L^(2)], (Delta v)/(Delta z)= [T^(-1)]`. |
