In one experiment showing that faster- moving objects have larger masses,
A) high- velocity rifle bullets are fired at targets and their impact is measured.
B) microscopic particles are released from rest in a gravitational field, and their acceleration is measured.
C) observers move along beside high- velocity rifle bullets, in order to measure the masses of the bullets.
D) a microscopic balance- beam is used to measure the speeds of particles emitted during radioactive decay.
E) high- speed microscopic particles pass through electromagnetic fields, and the bending of their path is measured.

Question

Quizplus · Accepted Answer

The bending of high-speed microscopic particles in electromagnetic fields is used to measure their mass, as the deflection depends on the mass and velocity of the particles.
