Q.4
Which of the following equations can be dimensionally incorrect.(Symbol have their usual notations)​

Answer 1

equation (B) is incorrect as my calculations

here dimentional formula of length, force, mass is

[L],[MLT-²],[M] respectively

[L]=[MLT-²]/[M]([MLT-²]²-[MLT-²]²)

[L]=[MLT-²]/[M]([M²L²T-⁴]-[M²L²T-⁴])

[L]=[MLT-²]/[M](0)

all of aboub equation is become zero

[L]=0 {incorrect relationship}
