Report | Ranjita asks : The gravitational Potential diff. b/w surface of planet & a point 20m above it is 16J/Kg.Calculate the work done in moving a 4kg body by 8m on a slope of 60degree from horizontal. |
Report | Shkmr2 asks : 2 equal positive charges r kept at points A and B . electric potential at points between A and B(excluding these points) is studied while moving from A 2 B. the potential: 1.increases 2. decreases 3 increses then decreses 4.decreses then increses.plz give d reason also |
Report | Shivani shukla asks : SOLVE THIS RIDDLE in some situations, i oppose the motion in other situations, i facilitate the motion but, i always oppose the relative motion between two moving surfaces. put some lubricant, and i become small there make the moving surfaces rough i make the movement tough i may be - static, sliding or rolling but whenever two surfaces are in motion i am always there, tell me who i am ! |
Report | Ankit asks : A walks down an escalator, moving in upward direction, and counts 150 steps. B walks up the same escalator and counts 75 steps. A takes three times as many steps in a given time as B. How many steps are there on the escalator? |
