Answer:
Ex= -17.1 N/C
Ey = +26.9 N/C
Explanation:
We apply formula of electric field:
Ep=k*q/d²
Ep: Electric field at point ( N/C)
q: Electric charge (C)
k: coulomb constant (N.m²/C²)
d: distance from charge q to point P (m)
In the attached graph we observe the directions of the electric field at P(0,0) due to q1 and q2
Calculation of the field at point P due to the load q₁
E₁=k*q₁/d₁² = 9*10⁹*4.25*10⁻⁹/1.080²= 32.8 N/C : Magnitude of E1
Direction of E₁ :Because the charge q₁ is negative the field enters the charge (+ y)
Calculation of the field at point P due to the load q₂
d₂=1.375 m
E₂=k*q₂/d₂² = 9*10⁹*3.80*10⁻⁹/ 1.375² = 18.09 N/C Magnitude of E₂
Direction of E₂ :Because the charge q₂ is positive the field leaves the charge in direction of angle β
, then,E₂ tiene componentes x-y en P.
E₂x=-E₂cos β= -18.09*(1.3/1.375)= -17.1 N/C
E₂y=-E₂sin β= -18.09*(0.45/1.375)= -5.9 N/C
Calculation of the electric field at point P located at the origin(0,0)
Ex=E₂x= -17.1 N/C
Ey=E₁y+E₂y =32.8 N/C -5.9 N/C = 26.9 N/C
The length of the pendulum is 0.087 m. Option d is correct.
<h3>What is Simple harmonic motion?</h3>Simple harmonic motion is periodic motion caused by a restoring force that is proportionate to the deviation from equilibrium.
Simple harmonic motion is periodic motion but many other conditions are dependent.
The time period of the pendulum is found as;
The length of the pendulum is 0.087 m
Hence, option d is correct.
