A tank is filled up to a height 2H WITH A LIQUID and is placed on a platform of height H from the ground .the distance x from the ground where a small hole is punched to get maximum range R is?
Ans) let the distance be x.then range(R)=2 . [(3H-x).x]^1/2 ......................... [ since t=(2x/g)^1/2 and v={2g(3H-x)}^1/2 ] R^2 = 4.(3Hx-x^2) for R to be max...R^2 should be max.hence differentiating and putting d(R^2)/dx=0.we get 3H-2x=0x=3H/2.
Electric field lines In good metallic conductors: In good metallic conductors: (i) Static electric fields are not there (zero inside a conductor) (ii) Charges reside
(i) These are positive ions having similar mass if the experimental gas does not have isotopes. However if the gas has substances then positive pulses are group of positive ions ha
