S = A(1 - {e^{ - Bxt}})

where S is speed and x is displacement. Then unit of B is

View answer and explanation

Correct option: A

{m^{ - 1}}{s^{ - 1}}

The correct answer is A (

{m^{ - 1}}{s^{ - 1}}

) because the exponent of 'e' must be dimensionless, so the units of Bxt must be 1. Therefore, the unit of B is inverse of x and t.
