Problem 1. An attractive force exists between two particles A and B with charges 2.062x10-4 C and -3.4518x10-4 C respectively. If particle B is positioned at coordinates (4cm,-2cm) from particle A (0,0), compute for the electrostatic force (both magnitude and direction) on the particle A due to particle B.

Three charged particles are placed at the corners of an equilateral triangle of side 1.20 m (see (Figure 1)). The charges are Q1​=7.4μC, Q2​=−8.2μC,       and  Q3​=5.6μC  . a ) Calculate the magnitude of the net force on particle 1 due to the other two

The figure shows an arrangement of four charged particles, with angle 0 = 30.0° and distance d = 1.50 cm. Particle 2 has charge q2 = 8.00 × 10-¹⁹ C; particles 3 and 4 have charges 93 94 = -4.80 × 10-19 C. (a) What is the distance D between the origin and particle 2 if the net electrostatic force on particle 1 due to the other particles is zero? (b) If particles 3 and 4 were moved closer to the x axis but maintained their symmetry about that axis, would the required value of D be greater than, less than, or the same as in part (a)? 1 (a) Number i (b) less d 3 4 D 2 Units

A charged particle A exerts a force of 2.40 ?N to the right on charged particle B when the particles are 12.4 mm apart. Particle B moves straight away from A to make the distance between them 16.2 mm. What vector force does particle B then exert on A? ?N to the left

Two charges, q₁=3.1 mC and q₂=1.6q₁ are placed along x axis so that q₁ is at the origin and 92 is at point (12.4, 0) cm. Where along the x axis is the net electric field equal to zero? Enter the x-coordinate of the position. Provide your answer in centimeters, with precision of three significant figures.

Three point charges, two positive and one negative, each having a magnitude of 35 micro-C are placed at the vertices of an equilateral triangle (57 cm on a side). What is the magnitude of the electrostatic force on the negative charge?
