Q1:

In Fig. the four particles form a square of edge length a = 5.00 cm and have charges q1 = +10.0nC, q2 = -20.0nC, q3 = +20.0nC and q4 = -10.0nC. In unit-vector notation. What net electric field do the particles produce at the squareâ€™s center?

Q2:

An electric field given by Eâ€™ = 4.0i^ â€“ 3.0(y2 + 2.0) j^ pierces a Gaussian cube of edge length 2.0 m and positioned as shown in Fig 23-7. (The magnitude E is in newtons per coulomb and the position x is in meters). What is the Electric Flux through the (a) top face (b) bottom face (c) left face and (d) back face? (e) What is the net electric flux through the cube?

Q3:

Figure shows a spherical shell with uniform volume charge density p= 1.84 nC/m3. Inner radius a= 10.0 cm and outer radius b= 2.00a. What is the magnetic of the electric field at a radical distances (a) r=0; (b) r=a/2.00; (c) r=a; (d) r= 1.50a; (e) r= b; and (f) r= 3.00b?

b) Ifa-b-2c, a+b-= 4c and c-3i+4j, then what are vector a and b? (*+2)

Q2:

Determine the voltage at each point with respect to ground in figure 01 and each resistor have 20 volts across it.

You throw a ball toward a wall at speed of 25.0 m/s and

angle is 0 = 40Â° above the horizontal as shown in figure 2

The wall distance d-22 m from the release point of the ball

How far above the release point does the ball hit the wall?

What are the horizontal and vertical componens of the

velocity as it hits the wall?

Question 03
