# Moving charged particle 3

**Electricity and Magnetism**Level 2

a) The speed of the charged particle at the position \(x=0.4 \text{ m}\) is twice as large as that at the position \(x=0.2 \text{ m}.\)

b) The electric field strength at the position \(x=0.7 \text{ m}\) is twice as large as that at the position \(x=0.2 \text{ m}.\)

c) The kinetic energy at the position \(x=0.8 \text{ m}\) is twice as large as that at the position \(x=0.6 \text{ m}.\)
