In a new system of units only the fundamental unit of length is changed: it is taken as 2m while the units of mass and time remain the same as in SI. By what factor will the numerical value of any acceleration change when expressed in this new system?
(a) It remains unchanged
(b) 4 times its SI value
(c) 21 of its SI value
(d) 2 times its SI value
