Q2. (ii) - (c)(a).... if voltmeter is attached in series then it has infinite resistance hence no current flows... but i dont know abt charge on capacitor maybe mathie can help... ya ya voltmeter reading will be 2V as well... uska jo side cell ke taraf hai us par potenial is 2V aur doosre taraf potential is 0V ... That's why no charge is developed on capacitor as well. as there is no pot. diff. across any end... both ends are at pot. zero.

prob no 3 ... at the topmost point if the net force is just zero it will complete the circle.....

or in other words mv²/2 = mg ............

or v= âˆš2g ......(1) .........

conserving energy .......

1/2m(2g) + mg(4) = 1/2 mu² .....

10mg = mu² .........

u = âˆš10g!!!!!

again 1/2mu² = 1/2(k)x²...........

(10)mg = 3x² ....
âˆš5/3=x .... pardon calc. mistakes[1]
