Answer:
a)2.59 ×10⁵ N/C
Direction is to the right.
b) 4.14 × 10⁻¹⁴ N , direction is to the Left.
Explanation:
Given:
Charge =
Charge =
Distance from the negative charge = 0.05 m
Distance to = 0.032 m
a) Electric field = E =
k = Coulomb's constant = 9 × 10⁹ N m²/C²
E = = (1.40625 × 10⁴ + 24.48 × 10⁴ ]
= 2.59 ×10⁵ N/C
Direction is to the right.
b) Force on the electron = Charge on the electron × Electric field E.
⇒ F = ( 1.6 × 10⁻19)(2.59 ×10⁵) = 4.14 × 10⁻¹⁴ N , direction is to the Left.
Answer:
D
Explanation:
It has the most "potential" to fall down because it is the highest relative to the ground.
Mass = 1kg
Distance = 1m
Time = 1s
Force= Mass x Acceleration due to graviy
= 1 x 9.8 = 9.8
Velocity = Distance / time
= 1 / 1 =1m/s
Power = Force x velocity
= 9.8 x 1 = 9.8 W
Answer:
While Rowing a boat, when you want to move forward on a boat, you paddle by pushing the water backwards, causing you to move forward. While Walking, You push the floor or the surface you are walking on with your toes, And the surface pushes your legs up, helping you to lift your legs up.
Explanation:
distance in meter= 15000 m
velocity of light v=3×10^8 m/s
time interval t= d/v
=
= 0.00005 sec
This is the time for the path in one direction. If you are looking for the time from the revolving mirror to the stationary mirror back to the revolving mirror, then it is twice the above value, which would be
2× 0.00005 = 0.0001 s
