| Re: Last year EAMCET Engineering paper
As you want EAMCET Engineering paper for doing preparation of this exam, so here I am giving you on your demand: The origin is translated to (1, 2). The point (7, 5) in the old system undergoes the following transformations successively. i) Moves to the new point under the given translation of origin ii) Translated through 2 units along the negative direction of the new X-axis iii) Rotated through an angle 4 p about the origin of new system in the clockwise direction. The final position of the point (7, 5) is A variable plane passes through a fixed point (1,2,3). Then the foot of the perpendicular form the origin to the plane lies on 1) a circle 2) a sphere 3) an ellipse 4) a parabola ANS : 2 Efficiency of a heat engine whose sink is at a temperature of 300 K is 40%. To increase the efficiency to 60%, keeping the sink temperature constant, the source temperature must be increased by 1) 750 K 2) 500 K 3) 250 K 4) 1000 K ANS : 3 The two surfaces of a concave lens, made of glass of refractive index 1.5 have the same radii of curvature R. It is now immersed in a medium of refractive index 1.75, then the lens 1) becomes a convergent lens of focal length 3.5 R 2) becomes a convergent lens of focal length 3.0 R 3) changes as a divergent lens of focal length 3.5 R 4) changes as a divergent lens of focal length 3.0 R ANS : 1 A microscope consists of an objective of focal length 1.9 cm and eye piece of focal length 5 cm. The two lenses are kept at a distance of 10.5 cm. If the image is to be formed at the least distance of distinct vision, the distance at which the object is to be placed before the objective is (Least distance of distinct vision is 25 cm) 1) 6.2 cm 2) 2.7 cm 3) 21.0 cm 4) 4.17 cm ANS : 2 EAMCET Engineering paper     For complete paper you can see following attachment............................ |
