a long solenoid carries a current of 2A.an electron is found to execute a uniform circular motion inside the solenod with a frequencyof 1*10 to power 8 rev/s.find the number of turns per metre in the solenoid?
Magneic field inside solonide B= mu_not*n*i where n is number of turns per unit length Frequence of electron = e/(2*pi*m*B) from frequency find B and then solve for n
