    minimum work done will be to lift up the barrel up with out doing any work to overcome friction... so it will be mgh.. 9.8*50*1.6...

    5... sir without any logic of acceleration... displacement can never decrease... if an object is falling down it must be covering some distance... so option D only remains... 13.. anticlockwise is equal to clockwise direction.... so F1D1=F2D2.. 900*.20 = F2 * 1.20.. F2 is 150N... 15... when...

    oh sorry mate... 150 was the frictional force given to us... and the force acting inclined to the motion was mgsin30... 200sin30= 100N...

    i have no idea abt 6TH one... 24... young modulus is a ratio and is constant for any particular material... it is clearly stated that same steel was used again so young modulus will be same again. that is E 30.... if u consider the electron coming out of the field, its horizontal component...

    work done by the person will be used to over come the frictional force and to move the object on an inclined plane... so this will bee equal to 150(3) + 100(3) = 750.... work done is force * distance... inclined distance moved is 3m... 1.5/.5 =3...

    V=IR.. in the middle part, for a small change in voltage, large current was produced... which outlines that resistance must have decreased... hope u got this....
