Answer: Units: C, T and Variables: <em>c, C, t, T</em>
(a) C is the unit of charge Coulomb, (e) T is the unit of magnetic field strength Tesla.
In physics, units are written straight and variables are written in italics. Various italic symbols are used for various quantities like <em>t </em>for time, <em>T</em> for temperature, <em>c</em> for any constant and <em>C</em> for curie constant.
Answer:
1.48×10⁻⁷ Newtons
Explanation:
From the question,
According to newton's law of universal gravitation.
F = Gmm'/r²........................ Equation 1
F = gravitational force, G = gravitational constant, m = mass of the first ball, m' = mass of the second ball, r = distance between the balls.
Given: m = m' = 8 kg, r = 17 cm = 0.17 m,
Constant : G = 6.67×10⁻¹¹ Nm²/kg²
Substitute these values into equation 1
F = (6.67×10⁻¹¹×8×8)/(0.17²)
F = 1.48×10⁻⁷ N
