Answer: 1.653 × 10⁴ N/C
Explanation: Given Q= 3.6× 10^-6
we assume there is a charge q placed at a distance r = 1.4m exerting an electric field strength towards Q.
Hence
F = kQq/r²
K= 9× 10^9
Now recall that E = F/q (electric field due to that charge)
E =( kQq/r²)/q
E = kQ/r² substituting the values gave the answer above.
Let the mass of the person be m. Total momentum is conserved (because the exterior forces on the system are balanced), especially the component in the vertical direction.
Given that,
Mass of gallon is M
Let man mass be m
Velocity of man is v
Let velocity if ballot be Vb
When the person begin to move we have
Conservation of momentum
mv + MVb=0
MVb=-mv
Vb= -(m/M) v
Given that the mass of man is less than mass of balloon. i.e. m<M
So, if m<M, then, m/M <1
Therefore, .
Vb= -(m/M) v
Vb< -v
This implies that the velocity of balloon is less than the velocity of man and if is also moving in opposite direction
So the man is moving upward, then the balloon is moving downward and it's velocity is less than the velocity of man,
The answer is C
Down with a speed less than v
Answer:
Answer is circular motion. Mark my answer brainliest
whats the example? That all yu should look it up on internet.
Answer:
1. Direction of B is parallel to V
2. Magnetic field is most uniform between the flat, parallel magnetic poles of a c-shaped magnet
3. Doubling B would double the magnitude of the force on the proton
4. Magnetic field is strongest near the north and south poles
5. The initial direction of the proton is toward the right of the screen. The field deflects the proton toward the top of the screen
6. Assume that you are viewing the diagram on a flat computer screen. Perpendicular to the screen, pointing toward you.
7. A stationary point charge doesn’t generate a magnetic field in the space around it.
8. Proton enters magnetic field at a speed of 7.8 x 10^4, charge of proton equal to 1.6 x 10^-19 is 2.6 x 10^-14 N
9. A few times every million years
10. Magnitude |q|vB directed towards bottom of screen
