Protons are released from rest in a Van de Graaff accelerator
system. The protons initially are located where the electric
potential has a value of 5.95 MV and then they travel through a
vacuum to a region where the potential is zero.
(a) Find the final speed of these protons.
m/s
(b) Find the accelerating electric field strength if the potential
changed uniformly over a distance of 2.60 m.
MV/m

Two equally charged particles, held 4.0 × 10-3 m
apart, are released from rest. The initial acceleration of the
first particle is observed to be 7.3 m/s2 and that of
the second to be 8.4 m/s2. If the mass of the first
particle is 8.5 × 10-7 kg, what are (a)
the mass of the second particle and (b) the
magnitude of the charge of each particle?

Two equally charged particles, held 4.0 × 10-3 m
apart, are released from rest. The initial acceleration of the
first particle is observed to be 5.5 m/s2 and that of
the second to be 9.0 m/s2. If the mass of the first
particle is 7.8 × 10-7 kg, what are (a)
the mass of the second particle and (b) the
magnitude of the charge of each particle?

Two equally charged particles are
held 4.1 ✕ 10−3 m apart and
then released from rest. The initial acceleration of the first
particle is observed to be 5.5 m/s2 and
that of the second to be 9.4 m/s2. The
mass of the first particle
is 6.3 ✕ 10−7 kg.
(a) What is the mass of the second
particle?
kg
(b) What is the magnitude of the charge of each
particle?
C
