Q1 Electrons with energy 80 keV are incident on the tungsten target of an X-Ray tube. K-shell electrons of tungsten have -72.5 keV energy. X-rays emitted by the tube contain only :a)A continuous X-ray spectrum with a minimum wavelength of 0.155 A b)A continuous X-ray spectrum (Bremsstrahlung) with all wavelengths.c)the characteristic X-ray spectrum of tungstend)A continuous X-ray spectrum (Bremsstrahlung) with a minimum wavelength of 0.155 A and the characteristic X-ray spectrum of tungsten

Q1:The value of i*(r*i) + j*(r*j) +k*(r*k) is (in terms of r):Q2: The force determined by the vector = (1, -8, -7) is resolved along three mutually perpendicular directions , one of which is the direction of the vector a=2i+2j+k. Then the vector component of the force in the direction of the vector a is :

Q1:A point taken on each median of a triangle divides the median in the ratio 1 : 3 , reckoning from the vertex . Then the ratio of the area of the triangle with vertices at these points to that of the original triangle is :Q2: If e1 and e2 are two unit vectors and q is the angle between them , then sin(q/2) is :Q3:The acute angle between the medians drawn from the acute angles of an isosceles right angled triangle is :

Q-1 One of the diameter of the circle circumscribing the rectangle ABCD is 4y = x + 7. If A and B are the points (-3, 4) and (5, 4), and slope of the curve at point (1, 1) be 2, then centre of circle is (in terms of a,b)Q-2 The point A on the parabola y2 = 4ax for which |AC - AB | is maximum, where B (0, a) and C (-a, 0) isQ-3 Consider the parabola 3y2 + 4y - 6x + 8 = 0. The points on the axis of this parabola from where 3 distinct normals can be drawn are given by

In an ideal double-slit experiment, when a glass plate (refractive index 1.5) of thickness t is introduced in the path of one of the interfering beams (wavelength ^), the intensity at the position where the central maximum occurred previously remains unchanged. The minimum thickness of the glass-plate is (in terms of ^)
