Question
The general equation of 2nd degree 9x2 –24xy + 16y2 – 20x –15y – 60 = 0 represents
- pair of st. lines
- parabola
- ellipse
- hyperbola
The correct answer is: parabola
As h = –12a = 9b = 16
h2 = ab
(–12)2 = 9.16
(–12)2 = 144 so it is parabola.

A disc of mass 2 M and radius R is placed on a fixed plank (rough) of length L. The coefficient of friction between the plank and disc is 
= 0.5. String (light) is connected to centre of disc and passing over a smooth light pulley and connected to a block of mass M as shown in the figure. Now the disc is given an angular velocity 
in clockwise direction and is gently placed on the plank. Consider this instant as t=0. Based on above information, answer the following questions : Mark the correct statement w.r.t. motion of block and disc.
