Question
Name the unit of physical quantity obtained by the formula `(2K)/v^2` Where K: kinetic energy, v: linear velocity
Advertisements
Solution
We know that kinetic energy K.E. = `1/2 mv^2`
`∴ (2K)/v^2 = 2 (1/2 mv^2)"/"v^2 = m(mass)`
Hence, the physical quantity obtained is mass and its unit is kilogram (kg)/g/any unit of mass.
