Answer:
6
Explanation:
Number of lines emanate from + 5 micro coulomb is 15 .
They terminates at negative charges that means at - 3 micro coulomb and - 2 micro Coulomb.
the electric field lines terminates at - 3 micro Coulomb and - 2 micro Coulomb is in the ratio of 3 : 2.
So the lines terminating at - 3 micro coulomb
= 
So the lines terminating at - 2 micro coulomb
= 
So, the number of filed lines terminates at - 2 micro Coulomb are 6.
Answer:
2.2 s
Explanation:
Hi!
Let's consider the origin of the coordinate system at the ground, and consider that the clam starts with zero velocity, the equation of motion of the clam is given by
We are looking for a time t for which x(t) = 0
Solving for t:
Rounding at the first decimal:
t = 2.2 s
Start at the big tree, and take the instructions
one at a time:
1). Walk 15 west.
2). From there, turn around and walk 2 east.
3). From there, walk 7 more east.
Where are you from the big tree now ?
Aren't you 6 west of it ?
I mean, let's see some common sense here !
Sliding and Static.
Would be the right one here.
Answer:
Fe = 25.67 N
Fg = 2.0734 x 10^-35 N
Explanation:
r = 3 x 10^-15 m
G = 6.67 x 10^-11 Nm^2/kg^2
Mp = 1.6726231 x 10^-27 kg
Qp = 1.6021 x 10^-19 C
K = 9 x 10^9 Nm^2/C^2
The formula for the electrical force between the two protons is given by
Fe = 25.67 N
The formula for the gravitational force between the two protons is given by
Fg = 2.0734 x 10^-35 N
