Charge q1 = 5.35·10-8 C is placed at the origin. Charges q2 = -1.47·10-8 C and q3 = 1.13·10-8 C are placed at points (0.161 m,0 m) and (0 m,0.273 m), respectively. a) Determine the magnitude of the net electrostatic force on charge q3. b) Determine the direction of the net electrostatic force on charge q3 (angle with respect to the positive x-axis).

What is the initial (horizontal) velocity of the ball.
Blocks with masses of 2.0 , 4.0 , and 6.0 are lined up in a row on a frictionless table. All three are pushed forward by a 57 N force applied to the 2kg block.How much force does the 4 block exert on the 6.0 block.
You have a 56.9-mF capacitor initially charged to a potential difference of 10.1 V. You discharge the capacitor through a 4.77-Ω resistor. What is the time constant? After what multiple of the time constant does the potential difference reach 2.47 V.
Find out the maximum distance d (along the ladder) that the monkey can climb up the ladder before rope breaks.
A transverse electromagnetic plane wave with a frequency of 2.84 MHz travels directly away from you (- z direction). At time t = 0, your magnetic field detector measures a magnetic field of 4.57 × 10-8 Tesla pointing down (- y direction) that further..
An electron with initial velocity v0 = 1.20 × 10^5 m/s enters a region 1cm long where it is electrically accelerated. It emerges with velocity v = 5.87 × 10^5 m/s. What is its acceleration, assumed constant? (Such a process occurs in conventional ..
