Answer:
200583.33 N/C direction opposite to that of the acceleration
Explanation:
m = Mass of object =
a = Acceleration of the object =
q = Charge =
E = Electric field
Here the inertia of the object will balance the electric force
The magnitude of the electric field is 200583.33 N/C and the direction is opposite to that of the acceleration.
Answer:
Velocity will be
Explanation:
We have given mass of alpha particle m = 4 u
Charge on alpha particle
Charge on thorium particle
Diameter is given as d = 15 fm
So radius
Potential energy is given by
From energy conservation
Answer:
it should be increase..
Explanation:
If temperature is held constant, the equation is reduced to Boyle's law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase.

atom is the smallest unit of an element that can or cannot exist freely. While on the other hand, a molecule is a set of atoms that are held together with the help of a bond and is the smallest unit of a compound. Furthermore, an atom can or cannot exist in a free state.
Answer:
(a) 10 s
(b) 30 m/s
(c) 150 m
Explanation:
The motorist's position at time t is:
x = 15t
The officer's position at time t is:
x = ½ (3) t² = 1.5 t²
(a) When they have the same position, the time is:
15t = 1.5 t²
t = 0 or 10 s
(b) The officer's speed is:
v = 3t
v = 30 m/s
(c) The position is:
x = 15t = 150 m
