The direction of the electric field shown in each part of Figure 24.5 is that produced by the charge distribution in the wire. Justify the direction shown in each part, using the Coulomb force law and the definition of E = F/q, where q is a positive test charge.

The direction of the electric field shown in each part of Figure is that produced by the charge distribution in the wire.
Answer to Problem 1CQ
- The direction of the electric field is upward
- The value of electric field is zero.
- The direction of the electric field is downward
- The direction of the electric field is upward
Given info:
Justify the direction shown in each part, using the Coulomb force law and the definition of E=F/q, where q is a positive test charge?
Explanation:
Positive charge moves from positive to negative, so the direction of electric field in part a is towards upper direction.
The distances between the positive and negative charge in part b is zero, so the electric field value is zero, so there is direction.
Positive charge moves from positive to negative, so the direction of electric field in part c is towards downward direction.
Positive charge moves from positive to negative, so the direction of electric field in part a is towards upper direction.
Conclusion:
The direction of the electric field shown in each part of Figure is studied.

- Required information A bungee jumper leaps from a bridge and undergoes a series of oscillations. Assume g = 9.78 m/s². If a 60.0-kg jumper uses a bungee cord that has an unstretched length of 30.1 m and she jumps from a height of 45.2 m above a river, coming to rest just a few centimeters above the water surface on the first downward descent, what is the period of the oscillations? Assume the bungee cord follows Hooke's law.arrow_forwardRequired information The leg bone (femur) breaks under a compressive force of about 6.50 × 104 N for a human and 12.3 × 104 N for a horse. The human femur has a compressive strength of 160 MPa, whereas the horse femur has a compressive strength of 140 MPa. What is the effective cross-sectional area of the femur in a horse? (Note: Since the center of the femur contains bone marrow, which has essentially no compressive strength, the effective cross-sectional area is about 80% of the total cross-sectional area.) cm2arrow_forwardno ai pleasearrow_forward

The bimetallic Pt-Ni nanoparticles are expected to decorate on the side surfaces of the aligned TiO2 nanorod arrays. These aligned TiO2 nanoarrays grew on the flat SiO2 monolith. Let's assume that the sizes of the Pt-Ni nanoparticles are > 10 nm. We further assume that you have access to a modern SEM that can produce a probe size as small as 1 nm with a current as high as 1 nA. You are not expected to damage/destroy the sample. Hint: keep your answers concise and to the point. TiO₂ Nanorods SiO, monolith a) What do you plan to do if your colleague wants to know if the Pt and Ni formed uniform alloy nanoparticles?
