Answer:
(a) Acceleration of positron is 6.03 x 10¹³ m/s²
(b) Speed of positron after 8.70 x 10⁻⁹ s is 5.24 x 10⁵ m/s
Explanation:
Given :
Constant electric field, E = 343 N/C
Mass of positron, m = 9.1 x 10⁻³¹ kg
Charge of positron, q = +e = 1.6 x 10⁻¹⁹ C
(a) Coulomb force on the positron is determine by the relation :
F = q x E ....(1)
But, force is also equals to product of mass and acceleration. So,
F = ma .....(2)
Here a is acceleration.
From equation (1) and (2).
m x a = q x E
Substitute the values of q, E and m in the above equation.
a = 6.03 x 10¹³ m/s²
(b) Initially, the positron is at rest, so its initial speed is zero.
The equation of motion for positron is :
v = u + at
Here v is final speed, u is initial speed and t is time.
Since, u is zero, so the equation becomes :
v = at
Substitute 8.70 x 10⁻⁹ s for t and 6.03 x 10¹³ m/s² for a in the above equation.
v = 6.03 x 10¹³ x 8.70 x 10⁻⁹ m/s
v = 5.24 x 10⁵ m/s
