Answer:
The strength of the electric field is
.
Explanation:
Given that,
Speed 
Time 
Angle = 45°
We need to calculate the acceleration
Using equation of motion




We need to calculate the strength of the electric field
Using relation of newton's second law and electric force



Put the value into the formula


Hence, The strength of the electric field is
.
