What is dimensional formula?
Hint – Dimension formula is
the expression for the unit of a physical quantity in terms of the fundamental quantities
. The fundamental quantities are mass (M), Length (L) and time (T). A dimensional formula is expressed in terms of power of M, L and T. … These will specify the nature of the unit and not its magnitude.
Which is the formula of potential difference answer?
The potential difference between points A and B, V
B
− V
A
, defined to be the change in potential energy of a charge q moved from A to B, is equal to the change in potential energy divided by the charge, Potential difference is commonly called voltage, represented by the symbol ΔV:
ΔV=ΔPEq Δ V = Δ PE q and ΔPE = qΔV
.
What is potential write its unit and dimensional formula?
Answer: Potential energy can be defined as the energy possessed by the body by virtue of its configuration or position. Mathematically, Potential energy (PE) = Mass(M) X Gravitational acceleration (g) X Altitude (h). … Dimensional formula of
gravitational acceleration= M0L1T-2
