A small charged sphere is attached to a thread and placed in an electric field. The other end of the thread is anchored so that

when placed in the field the sphere is in a static situation (all the forces on the sphere cancel). If the thread is horizontal, find the magnitude and direction of the electric field. The sphere has a mass of 0.018 kg and contains a charge of + 6.80 x 103 C. The tension in the thread is 6.57 x 10-2 N. Show your work and/or explain your reasoning. (20 pts)

Answer:

E = 9.66\times 10^{-6} N/C

direction is Horizontal

Explanation:

As we know that the string is horizontal here

so the tension force in the string is due to electrostatic force on it

now we will have

F = qE

so here the force is tension force on it

F = 6.57 \times 10^{-2} N

Q = 6.80 \times 10^3 C

now we have

6.57 \times 10^{-2} = (6.80 \times 10^3)E

E = 9.66\times 10^{-6} N/C

direction is Horizontal

You start walking from a point on a circular field of radius 0.5 km and 1 hour later
Feliz [49]

Answer:

1). average velocity= displacement/time

= here displacement is zero

= 0/1

= 0 m/s

2). average speed= total distance/time

=2πr/1

=(2×22/7×5/10)/1

22/7

3.14 km/h

Calculate the electric charge of the glass ball
-Dominant- [34]

Answer:

As per Coulomb's law we know that force between two charges is given as

F = \frac{kq_1q_2}{r^2}F=

r

here we know that

q_1 = 2.5 \times 10^{-6} Cq

C

q_2 = -5.0 \times 10^{-6} Cq

=−5.0×10

C

r = 0.0050 mr=0.0050m

now from above formula we will have

F = \frac{(9 \times 10^9)(2.5 \times 10^{-6})(5 \times 10^{-6})}{(0.0050)^2}F=

(0.0050)

F = 4500 NF=4500N

so they will attract towards each other as they are opposite in nature with force F = 4500 N

A meterologist made these observations one day:
Vinvika [58]

Answer:

They transfered more energy in the morning.

Explanation:

This is because, let me put this in simple words, you have more energy, you can run more laps around the track, right? This is the same with  the waves. They have more energy, so they can crash aganst the shore more!
