A physical quantity X depends on two other physical quantities A and B of same dimensions and unit as (1)/(x)=(1)/(A)+(1)/(B) If A=60+-2andB=30+-1 then percentage error in the measurement of X from A and B is

Write three physical quantities having dimensions [ML^-1 T^-2] .

A physical quantity A is dependent on other four physical quantities p,q,r and s as given by A=(sqrt(pq))/(r^(2)s^(3)) . The percentage error of measurement in p,q,r and s are 1%,3%,0.5% and 0.33% respectively, then the maximum percentage error in A is

" 3.Name the physical quantity whose dimension formula is same as "work'."1

A physical quantitiy X is related to four measurable quantities, a,b,c and d as give X=a^(2)b^(3)c^(5//2)d^(-2) . The percentage error in the measurement of a,b,c and d are 1%,2%,2% and 4% respectively. What is the percentage error in quantitiy X?

A : A dimensionless quantity may have unit. R : Two physical quantities having same dimensions, may have different units.

Let x={:[(a^(2)b^(2))/(c)]:} be the physical quantity. If the percentage error in the measurement of physical quantities a,b, and c is 2,3 and 4 per cent respectively, then percentage error in the measurement of x is

A physical quantity X is related to four measurable quantities a,b,c and d as follows X=a^2b^3c^((5)/(2))d^-2 . The percentage error in the measurement of a,b,c and d are 1%,2%,3% and 4% repectively. What is the percentage erroe in quantity X? If the value of X calculated on the basis of the above relation is 2.763, to what value should you round off the result.

A physcial quantity X is related to four measurable quantites a, b, c and d as follows : X = a^2 b^3 c^(5//2) d^(-2) The percentage error in the measurement of a, b, c and d are 1% , 2%, 3% and 4%, respectively. What is the percentage error in quantity X ? if the value of X calculated on the basis of the above relation is 2.763, to what value should you round off the result ?
