An individual homozgous for genes cd is crossed with wild type and F_(1) is crossed back with the double recessive. The appearance of the offspring is a follows: {:(++" "-" "903),(cd" "-" "897),(+d" "-" "98),(c+" "-" "102):} The distance between genes c and d is

A charged metalic sphere A is suspended by a nylon thread. Another charged metallic sphere B held by an insulating handle is brought close to A such that the distance between their centres is 10 cm, as shown in Fig. (a). The resulting repulsion of A is noted (for example, by shining a beam of light and measuring the deflection of its shadow on a screen). Spheres A and B are touched by uncharged spheres C and D respectively, as shown in Fig. (b). C and D are then removed and B is brought closer to A to distance of 5.0 cm between their centres, as shown in Fig. (c). what is the expected repulsion of A on the basis of Coulomb's law? Spheres A and C and spheres B and D have identical sizes. Ignore the size of A and B in comparison to the separation between their centres.

A physical quantity P is related to four quantities 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 ?

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% respectively. What is the percentage error in X?
