Q1/ Find the magnetic field strength (in Gauss) for a current of 3.7 A in the Helmholtz coils with 145 turn, assuming a coil radius of 15 cm. Express the answer with one decimal place. Q2/An electron is accelerated through an electric potential of 197 V, then enters a 31 Gauss magnetic field in a direction at a right angle to the magnetic field vector. Find the radius (in cm) of the subsequent circular path for this electron. Express the answer (without the unit) with two decimal places. Q3/ Two charges Q1 = 47 nC and Q2 = 23 nC are in rest on the horizontal axis. The distance between the charges is 0.74 m. What is the value of the magnetic field at the point between the charges which is 0.19 m away from charge Q1? Express the answer as a whole number. Q4/ Mark all that are correct: 1 N = 104 Tesla 1 H = 100 Teslas 1Tesla = 10-4 N 1 Tesla = 104 Gauss 1 Gauss = 10-4 Tesla 1 H = 10-4 Gauss 1 Gauss = 10000 Weber 1 N= 1000 Gauss 1 Gauss = 104 H 1 H = 10 Teslas

1 N = 104 Tesla
1 H = 100 Teslas
1Tesla = 10-4 N
1 Tesla = 104 Gauss
1 Gauss = 10-4 Tesla
1 H = 10-4 Gauss
1 Gauss = 10000 Weber
1 N= 1000 Gauss
1 Gauss = 104 H
1 H = 10 Teslas
