Question

two sphare of charge 2C and 3C and there masses are 2kg and 4kg. they are released from rest find velocity of 4kg when velocity of 2kg is 4m/sec.​

Answer 1

Answer:

2m/sec

Explanation:

taking both sphere as system

electrostatic force will become internal

momentum conservation

initial momentum=final momentum

2m*0+4m*0=2m*4+4m*x

x=2m/sec in negative x dirn.
