balancing vertical forces ,we get :
(2m+M)g =N(by grd on M) +N'(by grd on m)
balance torque about any pt. on stick nd get second eqn
solve to get d ans !
|
|
|
|
see, L(initially)= L(finally)
b'coz no external torque is acting on d system(i.e. man+ platform +weights)
let m = mass of weights, r = 90cm,R=20 cm, w:old angular velocity , W:new angular velocity , I :moment of inertia of the man together with the platform
so, (I+2mr^2)w =(I+2mR^2)W
solve to get d ans !
|
|
|
|
as v=const then on inc temp , pressure should also inc ! with slope remaining constt

Hey can u xplain what this assistance is??????
|
|
|
|
|
NaOH + CaO
|
|
|
|
|
since wolf kishner requires a basic medium to work nd as most compds react with acids so it is preffered
|
|
|
|
|
i got d ans it's (c) nd(d)
|
|
|
|
|
yeah it's (a).
|
|
|
|
repulsive force inc so increases
|
|
|
|
apply Lenz law 2 get (2) as the ans
|
|
|
|
|
(1) nd kunal, slope can vary coz it maynot be an elastic collison!
|
|
|
|
|
it has to be (1)
|
|
|
|
|
(2) using perpendicular axis thm

Q a particle of specific charge(charge/mass) L starts movin? from origin under action of an electric field  nd magnetic field B k cap. its velocity at (x,0,0) is (4  ) the value of x =?
Ans: 25/(2LE)
I know how 2 solve using work energy thm but how 2 solve via Lorentz force????

(c) only torque
(d) neither force nor torque
Explain!!!!

Lower surface of a rectangular plank is rough nd lying at rest on a rough horizontal surface .upper surface of plank is smooth nd has a smooth hemisphere placed over it thru a lite string. After string is burnt, trajectory of C.M. of sphere is :
(a) circle
(b) ellipse
(c) st. line
(d) parabola
pls. giv detailed xplanation.

How to hav grip in Electricity & Magnetism?????????
|
|
|
|
inversely
|
|
|
|
use
 \;= \int_{a}^{b}f(a%2Bb-x) [Eqn]\;) 
[/Eqn]dx-\;\int_{a}^{ b}log2dx)
and put 2x=t and change limits accordingly
ans=  /2 log 2

If thermal expansion properties of water were like those of other liqds:
(a) boiling point of water wud increase with increase in altitude
(b) water wud become more dense as its temp. is increased to boiling point.
(c)ice wud become more dense as its temp.is increased.
(d) ice wud form on bottom of a body of water before it is formed on top.
ans is (D)
please give an explanation.....

A cylindrical container of radius R & height h is completely filled with a liqd. 2 horizontal L shaped pipes of small cross section a are connected to cylinder at a distance h/2 from each d edge of the cylinder . now 2 pipes are opened & the fluid starts coming out of d pipes horizontally in opp. directions .then torque due to ejected liqd on system is........(the cylinder is vertically aligned and one end of it is tied to a rigid support)sorry can't give the diag.
ans is 4kghR where k : density of liqd.
