Question 5 A \( 2.0 \times 10-6 \mathrm{C} \) charge is located halfway between an \( 8.0 \times 10-6 \mathrm{C} \) charge and \( \mathrm{a}-5.0 \times \mathrm{x} \) \( 10-6 \mathrm{C} \). Find the net force on the \( 2.0 \times 10-6 \mathrm{C} \) charge. 5. Un cuerpo que se mueve con una velocided de \( 10 \mathrm{~m} / \mathrm{s} \) es uniformemente desace:erado hasta detenerse dentro de una distancea de 20 m . a) ¿Cuál es el valor do la desaceleracion? b) ¿Cuánto tiempo viajo antes de detenerse? 5.- Un cuerpo que se mueve con una velocidod de \( 10 \mathrm{~m} / \mathrm{s} \) es uniformemente desacelerado lasta detenerse dentro de una distanca de 20 m a) ¿Cual es el valor de la desaceleración? b) ¿Cuánto diempo viajó antes de detenerse? Un movil A tiene una velocidad de \( 32 \mathrm{~m} / \mathrm{s} \), Otro móvil B recorre 350 km en 3 horas y un ancer móvil C tarda 10 minutos en recorrer 19 km . ¿Cuál es of más veloz? Question 4 Two point charges, \( 2.5 \times 10-6 \mathrm{C} \) and \( -5.0 \times 10-6 \mathrm{C} \), are placed 3.0 m apart. What is the magnitude of the electric field at point \( P \), midway between the two charges? \( 2.5 \times 10^{-6} \mathrm{C} \) Question 4 Two point charges, \( 2.5 \times 10-6 \mathrm{C} \) and \( -5.0 \times 10-6 \mathrm{C} \), are placed 3.0 m apart. What is the magnitude of the electric field at point \( P \), midway between the two charges? \( 2.5 \times 10^{-6} \mathrm{C} \) Esercizio: Sia dato un'auto che si trova a distanza di 50 km da Roma e dopo 1h si trova a 200km da Roma, dopo due ore si trova a 350km da Roma, dopo tre ore a 500 km da Roma scrivere la legge s = s(t) vista da un osservatore che si trova a Roma, che tipo di legge è? Darne la rappresentazione grafica. Trovare dove si troverà dopo 4 ore e mezzo. Scrivere la stessa legge però ponendo l'origine del sistema di riferimento questa volta nel punto da cui è partita l'automobile, che tipo di legge è? Trovare dove si troverà dopo 4 ore e mezza rispetto a questo sistema di riferimento. Verifiche orali Dados los vectores: \( \vec{u}=3 i-j+7 k \) \( \vec{v}=4 i+5 k \) \( \vec{w}=-5 i+2 j-k \) El producto \( (\vec{v} \cdot \vec{w}) \) multiplicado por el vector \( \vec{u} \) está representado por: 1. A ciarge of \( 2 \mu \mathrm{C} \) is placed 0.1 m away from another charge of \( -3 \mu \mathrm{C} \). Using Coulomb's law. calculate the force between them. (Assume \( \left.k=8.99 \times 10^{9} \mathrm{~N} \mathrm{~m}^{2} / \mathrm{C}^{2}\right)(5 \mathrm{Marks} \) ) Calculate the electric field at a point where a \( 5 \mu \mathrm{C} \) charge experiences a force of 0.2 N . ( 5 Marks) An 1 C voltage of \( V(t)=220 \sin (100 \pi t) \) is applied to a \( 50 \Omega \) resistor. Calculate the pecie current through the resistor. ( 5 Marks) A capacitor with a capacitance of \( 20 \mu \mathrm{~F} \) is connected in an AC circuit with a frequency of 50 Hz . Calculate the capacitive reactance. ( 5 Marks ) Two forces of magnitude 30 newtons \( (N) \) and 60 N act on an object at angles of \( 30^{\circ} \) and \( -45^{\circ} \) with the positive \( x \)-axis as shown in the figure. Find the direction and magnitude of the resultant force; that is, find \( F_{1}+F_{2} \). \( F_{1}+F_{2}=(\square) \mathbf{i}+(\square) \mathbf{j} \) (Simplify your answer, including any radicals.
