A charged bead of 4 micro columb is threaded on a fixed smooth circular ring of radius 2m in gravity free space . Another same charge is fixed at 1m from center . the bead is projected with such sufficient velocity to complete the circular path . If the mass of bead is 100gm . what is initial speed v? 80 root 3 cm/sec 40 root2 cm/sec 10 m/s 4 root 5 m/sec

Dear student 
At first, we have to find a situation in which the bead completes a circle after that we can easily solve using law of conservation of energy.
Plese attach an image.
Good Luck
