Sorry if this is the wrong place to post this, but I wasn't sure where exactly to put it. When we calculate the force on a closed loop of current-carrying wire in a uniform magnetic field, We calculate the line integral of the loop to be 0. However, when we evaluate the line integral for an...

Consider which forces are causing the prism to move, and which forces are causing the blocks to move. Remember the blocks move with the resultant acceleration of a and a0.

got it now, thanks everybody for the help!

How would you go about calculating the velocity in this case? I know dV=a dt but i don't know how a varies with time...

I get it now, so as the string stretches, the restoring force increases and so does the deceleration from the spring.

isnt this applicable whenever acceleration is constant? or am i missing something...

v²=u²+2as (constant acceleration) Since motion starts from rest, u=0.

EDIT: Also, i have seen valid solutions using energy conservation but, no solutions with tensions..

Homework Statement A given pulley has a radius of 20 cm and moment of inertia 0.2 kgm2. The string going over it is attached to a vertical spring of spring constant 50 N/m on one end and a 1 kg mass on the other end. The system is released from rest with the spring at natural length. Find the...

In Oersted's Experiment, when a compass needle was placed parallel to the wire, then deflection was observed. why was this not observed when the compass needle was perpendicular?
