The axis is parallel to Xaxis.and centre of mass of hemisphere is at (0,3R/8)

plz xplain conditions for cyclisation in org reactions with suitable examples

moment of inertia of a sphere about an axis through its centre is 2/5 mr^2how does it change when half of the sphere is cut off?if we take center of sphere as origin,. centre of mass of hemisphere is 3R/8 from origin.what is moment of inertia of hemisphere about an axis through this center of mass?

URGENT!!!!!!!!!!! EXAM TMRW2 mirrors are inclined at an angle 50 degree.An object is placed such that line joining object and joint of 2 mirrors is inclined at an angle 30 degree with lower mirror.how to find number of images formed by each mirror?(not total number of images))

plzzzz i want help ....................

is there anyone i've been waiting for so looooooooooong

when does colour of aniline becomes brownish red?is it due to oxidation?

thanks i got the answer. the problem was that i couldnt get the difference b/w surface and line integral.in gauss theorem we consider a 2D surface around the conductor but in amperes theorem we consider a loop sorrounding the conductor.. for a solenoid if we consider a loop sorroundig it the net current through it is zero.. so field outside is zero. am i correct? fastplzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

also if we consider aloop inside the solenoid there is no current through it. but thre is field inside . why is it so?
