1.	If the units of length and time are doubled, what will be the factor by which the unit of acceleration will change?(a) 1(b) 0.25(c) 0.5(d) 2The question was posed to me during an online interview.The above asked question is from Dimensional Formulae and Equations topic in chapter Units and Measurements of Physics – Class 11
Answer» Right answer is (c) 0.5 For explanation: The DIMENSIONS of acceleration are LT^-2. On DOUBLING both LENGTH and time, the NEW dimensions become (0.5)*LT^-2.
