Q1. Charge A and charge B are 2.5 m apart. Charge A is 1.4C and charge B is 2.5C. Charge C, that is 2.0 C, is located between them and the force on charge C is zero. How far from charge A is Charge C?
Q2. A 2.0-C charge moves with a velocity of (2.0i + 4.0j + 6.0k) m/s and experiences a magnetic force of (4.0i - 20j + 12k) N. The x component of the magnetic field is equal to zero. Find out the y component of the magnetic field.
