These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following five reponses (a) If both Assertion and Reason arecorrect and Reason is the correct explanation of Asserrtion. (b) If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion. (c ) If Assertion is true but Reason is false. (d) If Assertion is false but Reason is true. Assertion At any instant the magnitude of rate of change of potential energy of the projectile of mass 1 kg is numerically equal to magnitude of a.v (where a is acceleration due to gravity and v is velocity at that instant) Reason The graph representing power delivered by the gravitational force acting on the projectile with time will be straight line with negative slope.

A particle executes SHM on a straight line path. The amplitude of oscillation is 2cm . When the displacement of the particle from the mean position is 1cm , the numerical value of magnitude of acceleration is equal to the mumerical value of velocity. Find the frequency of SHM (in Hz ).

The area of a triangle ABC is one unit. DE is a straight line parallel to BC , joining the points D and E on AB and AC respectively such that AD : DB = 1 : 6. The ratio of the areas of the triangles ADE and ABC is : एक त्रिभुज ABC का क्षेत्रफल 1 इकाई है | DE, BC के समानांतर एक सीधी रेखा है जो क्रमशः AB और AC पर स्थित बिंदु D तथा E को इस प्रकार जोड़ती है कि AD : DB = 1 : 6 है | त्रिभुज ADE और ABC के क्षेत्रफल में अनुपात ज्ञात करें |

Five persons Lopa, Kripa, Sumi, Jani and Sush are sitting in a straight line facing north. Sush is to the immediate left of Sumi, Jani is to the immediate right of Lopa. Kripa is between Sush and Jani. Who is sitting between Lopa and Kripa? पाँच व्यक्ति लोपा, कृपा, सुमी, जानी तथा सुष एक सीधी रेखा में उत्तर की ओर मुख करके बैठे हुए हैं। सुष, सुमी के तुरंत बाएँ को है, जानी, लोपा के तुरंत दाएँ को है। कृपा सुष तथा जानी के बीच है। लोपा तथा कृपा के बीच कौन बैठा हुआ है?
