If the nuclear force between two protons, two neutrons and between proton and neutron is denoted by ' and respectively, then

Binding energy per nucleon plot against the mass numberfor stable nuclei is shown in the figure. Which curve iscorrect?

If the D. C’s of a line are then c is equal to

For such questions, we should know the properties of direction cosines.

The value of f(0) , so that the function  becomes continuous for all is given by

Let f, g: R  R be two functions defined by and g(x) = x f(x)
Statement 1: f is a continuous function at x = 0
Statement 2: g is a differentiable function at x = 0

lf x2 and A and 8 are respecively the maximum and the minimum values of , then (A, B) is equal to
