प्रश्न
For proton acceleration, a cyclotron is used in which a magnetic field of 1.4 Wb/m2 is applied. Find the time period for reversing the electric field between the two Ds.
उत्तर
Data: B= 1.4 Wb/m2 , m = 1.67 × 10-27 kg,
q = 1.6 × 10-19 c
T = `(2pi"m")/("qB")`
t = `"T"/2 =(pi "m")/"qB" = (3.142(1.67 xx 10^-27))/((1.6 xx 10^-19)(1.4))`
= 2.342 × 10-8 s
