SUMMARY
The electric field between deflection plates in a TV tube can be calculated using the force experienced by the electron beam. Given a force of 3.0 x 10-6N, the electric field (E) can be determined using the formula E = F/q, where F is the force and q is the charge of the electron. Additionally, when a globe acquires a charge of -8.0 x 10-9C, the electric field at a distance of 0.40m can be calculated using the formula E = k * |Q| / r2, where k is Coulomb's constant, Q is the charge, and r is the distance from the charge. Gauss's law simplifies the calculation by allowing the assumption of uniform charge distribution over the sphere.
