The units of length, velocity and force are doubled. Which of the following is the correct change in th other units?

Options

A. Unit of time is doubled
B. Unit of mass is doubled
C. Unit of momentum is doubled
D. Unit of energy is doubled

Answer

C

Explanation

Since units of length, velocity and force are doubled.
Hence, `["m"]=(["force"]["time"])/(["velocity"])`,
`["time"]=(["length"])/(["velocity"])`
Hence, unit of mass, and time remains same.
Momentum is doubled.
