Expert Solution
Step 1: Given data

Magnitude of electric field is E equals 50 space straight N divided by straight C

Initial velocity of electron is u equals 56 space km divided by straight s

Note:

Charge on one electron is q equals negative 1.6 cross times 10 to the power of negative 19 end exponent space straight C

1 space straight N equals 1 space kg times straight m divided by straight s squared

1 space km equals 1000 space straight m

1 space straight s equals 10 to the power of 9 space ns

Find:

(a) Electron's speed after time t equals 1.6 space ns

(b) Distance traveled by electron in time t equals 1.6 space ns
