Step 1

Part A: help_outlineImage TranscriptioncloseGiven info: Potential difference is 600 V. The distance between the plates is 5.33 mm. Explanation: Formula to calculate the electric field between the plates is, E =|-| AV Az Ax is the distance. AV is the potential difference. Substitute 5.33 mm for Ax and 600 V for AV E =|- 600 V 5,33 mm 600 V 5.33x10-³m = 1.13 x 10°N/C %3D Conclusion: The magnitude of electric field is 1.13 x 105N/C. fullscreen
Step 2

Part B: help_outlineImage TranscriptioncloseGiven info: Potential difference is 600 V. The distance between the plates is 5.33 mm. Explanation: Formula to calculate the electric force is, F = eE • e is the elementary charge. Substitute 1.6 x 10-19C for q and 1.13 x 10°N/C for E. F = (1.6 x 10-19C) (1.13 × 10°N/C) = 1.80 x 10¬14N Conclusion: The electric force on the electron is 1.80 x 10-14N. fullscreen
Step 3

Part C:... help_outlineImage TranscriptioncloseGiven info: Potential difference is 600 V. The distance between the plates is 5.33 mm. The displacement of the electron is 2.90 mm. Explanation: Formula to calculate the work done is, W = FAx cos 0 O is the angle between the force and displacement. Aæ is the total displacement. The total displacement is, Ax = (5.33 mm) – (2.90 mm) = 2.43 mm Substitute 1.80 × 10-14N for F, 2.43 mm for Ax and 0° for 0. W = (1.80 x 10-14N) (2.43 mm) cos 0° = (1.80 x 10-14N) (2.43 × 10–³m) cos 0° = 4.37 × 10-17J fullscreen
