The dimensional formula for a physical quantity x is [M^(-1)L^(3)T^(-2)] . The errors in measuring the quantities M ,L and T respectively are "1%" each.Then maximum percentage error that occurs in measuring the quantity 'x' is

A physical quantity X is represented by X = (M^(x) L^(-y) T^(-z) . The maximum percantage errors in the measurement of M , L , and T , respectively , are a% , b% and c% . The maximum percentage error in the measurement of X will be

The dimensional formula for a physical quantity x is [M^(-1) L^(3) T^(-2) ] . The errors in measuring the quantities M , L , and T, respectively are 2%, 3% , and 4% . The maximum percentage of error that occurs in measuring the quantity x is

A physical quantity is given by X=M^(a)L^(b)T^(c) . The percentage error in measurement of M,L and T are alpha, beta and gamma respectively. Then maximum percentage error in the quantity X is

In a class , 22 studets offered Mathematics , 18 students offered Chemistry and 24 students offered Physics . All of them have to offer atleast one of these . 11 are in both Mathematics and Chemistry ,13 in Chemistry and Physics and 14 in Mathematics and Physics and 7 have offered all the three subjects Find : (i) how many students are there in the class ? (ii) how many students offered only Mathematics ?

A standard cell of emf e_(0)=1.11 V is balanced against 72 cm length of a pootentiometer. The same potentiometer is used to measure the potential difference across the stndard resistance R=120 Omega . When the ammeter shows a current of 7.8 mA, a balanced lengh of 60 xm is obtained on the potentiometer. (i) Determine the current following through the resistor. (ii) Estimate the error in measurement of the ammeter.
