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 .
The current drawn by the series circuit is(R₁ + R₂)/R₁R₂ times the current drawn by the parallel circuit.
Let the resistance of the two lamps are R₁ and R₂.
Then the equivalent resistance in series combination is: R = R₁ + R₂.
And, the equivalent resistance in parallel combination is:
r = R₁R₂/(R₁ + R₂).
So, if the supply voltage is V,
Then, current drown in series combination; = V/R = V/(R₁ + R₂)
And, current drown in parallel combination; = V/r = V(R₁ + R₂)/R₁R₂
So , = [ V/(R₁ + R₂)] /[V(R₁ + R₂)/R₁R₂]
= (R₁ + R₂)/R₁R₂
Hence, the ratio of current drawn in series and current drown in parallel is (R₁ + R₂)/R₁R₂. So, he current drawn by the series circuit is(R₁ + R₂)/R₁R₂ times the current drawn by the parallel circuit.
