Question
An electron with an initial velocity $v_{0}=1.50 \times 10^{5} \mathrm{~m} / \mathrm{s}$cnters a region of length $L=1.00 \mathrm{~cm}$ where it is electrically accelerated (Fig. $2-26$ ). It cmerges with $v=5.70 \times 10^{6} \mathrm{~m} / \mathrm{s}$. What is its acceleration, assumed constant?
Step 1
50 \times 10^{5} \mathrm{~m} / \mathrm{s}$, the final velocity $v=5.70 \times 10^{6} \mathrm{~m} / \mathrm{s}$, and the length of the region $L=1.00 \mathrm{~cm}$. We are asked to find the acceleration, assuming it is constant. Show more…

Constant Acceleration An electron with an initial velocity $v_{0}=1.50 \times 10^{5} \mathrm{m} / \mathrm{s}$ enters a region of length $L=1.00$ $\mathrm{cm}$ where it is electrically accelerated (Fig. $2-26 )$ . It emerges with $v=5.70 \times 10^{6} \mathrm{m} / \mathrm{s} .$ What is its acceleration, assumed constant?
An electron with initial velocity $v_{1}$ $=1.50 \times 10^{5} \mathrm{~m} / \mathrm{s}$ enters a region $1.0 \mathrm{~cm}$ long where it is electrically accelerated (Fig. $2-26$ ). It emerges with velocity $v_{2}=5.70$ $\times 10^{6} \mathrm{~m} / \mathrm{s}$. What is its acceleration, assumed constant? (Such a process occurs in conventional television sets.)
An electron with initial velocity v0 = 1.67 × 105 m/s enters a region 1.0 cm long where it is electrically accelerated. It emerges with velocity v = 5.25 × 106 m/s. What is its acceleration, assumed constant?
