plssss plsssssssss solve it
|
|
|
|
no im just giving u an example to prove my point,
ur right that in exams the chapter will not be given
but i dont understsand how the principle of colisions has been applied
|
|
|
|
|
this sum from the chapter work,energy,power so no collisions r discussed in this chapter
|
|
|
|
|
|
see energy is not conserved only when a non conservative force acts on it(friction). i dont think any friction is acting here
|
|
|
|
|
hey dudes ols solve it its extremely urgent
|
|
|
|
see i made a mista ke 1/2mv^2=(M+m)gh
see ganesha only the bullet is moving with a velocity v
so it cant be 1/2(m+M)v^2
|

SORRY THE PICTURE IS NOT BEING POSTED PLSSS SOLVE
|

A CHARGE 1 uc IS GIVEN TO A PARALLEL PLATE CAPACITOR OF CAPACITANCE O.2uf AND A CHARGE 2uc IS GIVEN TO THE OTHER PLATE. FIND THE POTENTIOL DIFFERENCE BETWEEEN THE PLATES
|
|
|
|
|
|
so how can u solve it withouth equating the forces
|
|
|
|
|
let the tension in both the strings be T
the only formula im getting is
2Tcosa=mg
|
