Answer:
(a). The magnitude of the acceleration of the proton is
(b). The initial peed of the protion is
(c). The time is .
Explanation:
Given that,
Electric field
Time = 5.0 sec
Distance 7.00 cm
(a). We need to calculate the acceleration
Using formula of force
Where, E = electric field
m = mass of proton
q = charge of proton
Put the value into the formula
The magnitude of the acceleration of the proton is
(b). We need to calculate the initial peed
Using equation of motion
Where, s = distance
Put the value into the formula
The initial peed of the protion is
(c). We need to calculate the time interval over which the proton comes to rest
Using formula
Where, u = initial velocity
a = acceleration
Put the value into the formula
Hence, (a). The magnitude of the acceleration of the proton is
(b). The initial peed of the protion is
(c). The time is .
