Ramesh, a student of physics visited a park with his teacher, where he saw fountains of different colours as red, yellow, green, orange, blue, violet, white and Indigo. He was very happy by observing this beautiful scene and thankful to his teacher for providing this opportunity. His teacher asked Ramesh to assume the refractive index of the colourful water as 1.29, 1.33, 1.34, 1.35, 1.32, 1.36, 1.30 and 1.33 respectively. On the basis of his knowledge of physics, his teacher asked him to answer the following questions: Q1(i) Find mean value of refractive index * 1 point a) 1.33 b) 1.57 c) 2.26 d) 1.29 Q2(ii) Find mean absolute error in measurements * 1 point a) 0.0175 b) 1.5990 c) 0.0264 d) 1.2922 Q2(iii) Calculate fractional error (relative error) * 1 point a) 0.015 b) 1.090 c) 0.002 d) 0.292 Q2(iv) Calculate percentage error * 1 point a) 2% b) 3% c) 4% d) 5% Q2(v) is true vale equal to mean value * 1 point a) Yes b) No
