Question

A proton moves with a velocity of 5 x 106 j m/s, through the uniform electric field E = 4 x 106 (2i + 0.2j + 0.1k) Vm-1and the uniform magnetic field B = 0.2( i + 0.2 j + k) T. The approximate net force acting on the proton is

• A. .2 x 10-13 N
• B. 5 x 10-13 N
• C. 2.0 x 10-13 N
• D. 25 x 10-13 N
