Two positive charges 12pC and lOpC . are initially separated by 10cm. Calculate the work done in bringing the two charges 4 cm closer Solution The charges are q, = 12 X I0""C and q 2 = 10 X ..

Solution: Arranging the data in ascending order, we have 3, 3, 5, 8, 9, 10, 12, 12, 12, 18, 21, 21 Since n = 12, the median is the mean of 6 th and 7 th value. Median(M) = $\frac{10 + 12}{2}$ = 11 We can compute the mea..

Methane (i) It is a colourless and an odourless gas. (ii) Its melting point is -183 C and its boiling point is -162 C. (iii) It is negligibly soluble in water and soluble in organic solvents. Like carbon dioxide molecules, methane molecules also absorb outgoing heat radi..
