Answer:Force on -7 uC charge due to charge placed at x = - 10cm
now we will have
towards left
similarly force due to -5 uC charge placed at x = 6 cm
now we will have
towards left
Now net force on 7 uC charge is given as
towards left
Explanation:
Hello!
Use the formula:
W = Fd
Replacing:
W = 300 N * 300 m
Resolving:
W = 90000 J
The work is <u>90000 Joules.</u>
Answer:
momentum=mass×velocity
momentum =400kg×20m/s=8000kg.m/s
Answer
given,
current (I) = 16 mA
circumference of the circular loop (S)= 1.90 m
Magnetic field (B)= 0.790 T
S = 2 π r
1.9 = 2 π r
r = 0.3024 m
a) magnetic moment of loop
M= I A
M=
M=
M=
b) torque exerted in the loop
