A 10\(\mu\)C charge moves with a velocity of 1.0 x 105 ms-1 at right angle to a uniform magnetic field of flux density 5.0 x 10-4T. Calculate the force on the charge
5.0 x 10-5N
5.0 x 10-4N
5.0 x 105N
5.0 x 106N
คำอธิบาย
F = qvB
= 10 x 10-6 x 1.0 x 105 x 10-4
= 5.0 x 10-4N
= 10 x 10-6 x 1.0 x 105 x 10-4
= 5.0 x 10-4N
