Suppose Ram has placed a ball in front of a concave mirror of focal length (f) at various distances (u) and he has measured the corresponding image distances (v). From the values of u and v, Ram is able to plot a graph of \( \frac{1}{v} \) against \( \frac{1}{u} \). From the graph, Ram has observed that x-intercept and y-intercept are 0.1 cm and 0.11 cm, respectively. Then the focal length of the mirror is:
If x = b + c , y = c - a , z = a - b , then find the value of x2 + y2 +z2 - 2xy - 2xz + 2yz.
