A physical quantity P is related to four observables a, b, c and d as follows P=(a^(3)b^(2))/((sqrt(c)d)). The percentage errors of measurement in a, b, c and d are 1%, 3%, 4% and 2%. respectively. What is the percentage error in the quantity P? If the value of P calculated using the abovc rclation turns out to be 3.763, to what value should you round off the resultr? |
