Of the following quantities , which one has the dimensions different from the remaining three?A. Energy densityB. Force per unit areaC. Product of charge per unit volume and voltageD. Angular momentum per unit mass |
|
Answer» Correct Answer - D Energy density `= ("Energy")/("Volume") = [ML^(-1)T^(-2)]` `"Force//Area" = ML^(-1)T^(-2) ["Charge // Volume"] xx ["Voltage"]` `= (Q)/( vol.) xx (W)/(Q) = ("Work")/("Volume") = ML^(-1)T^(-2)` The dimensions of `(d)` are different , i.e., `(ML^(2)T^(-1))/(M) = M^(0)L^(2)T^(-1)` Hence , correct choice is `(d)`. |
