Concepts Of Physics MCQ Edition [Volume 1]PhysicsIntroduction to Physics
Determine the dimensions of electric dipole moment p . The defining equation is p = q d , where d is distance and q is charge.
Options
- AL^2TI
- BLT⁻¹I
- CL^2I
- DLTI
Correct answer
D. LTI
Step-by-step solution
The defining equation for electric dipole moment is p = q d . The dimensions of charge q are given by current time, which is [I T] . The dimensions of distance d are [L] . Substituting these into the equation, we get [p] = [I T] [L] = [L T I] . Thus, the dimensions of electric dipole moment are LTI .
