OK don't be panic... yarr spend one night there then u may leave on Friday
Hahaha scary dark night and u are alone in ur room nd also in a corridor... I know boys hostel is empty now
I don't want to talk any one of u. =_=
seriously aww!!! by the way have u given ur project name to chemistry lab in charge
no not yet.
now I think I will give in evening
thanks for reminding
it's good that I stopped
Hahaha
OK bye

Answer:
a) 1.64 × 10⁻²⁶N , 2.4 * 10⁻¹⁶ N
Explanation:
Given:
q = -2 * 10⁻⁹ C
Fe = 3 * 10⁻⁶ N
we know, F = qE
=> 3 * 10⁻⁶ N = -2 * 10⁻⁹ C * E
=> E = -1.5 * 10³ NC⁻¹ [Negative sign shows that field is in opposite direction of Force. i.e; in upward direction]
|E| = 1.5 * 10³ NC⁻¹
Charge on proton = +1.6 * 10⁻¹⁹ C
Fe = qE
=> Fe = +1.6 * 10⁻¹⁹ C * 1.5 * 10³ NC⁻¹ = 2.4 * 10⁻¹⁶ N
---------------------------
Mass of proton = 1.64 × 10⁻²⁷ Kg
Fg = mg
=> Fg = 1.64 × 10⁻²⁷ Kg * 10 m/s² = 1.64 × 10⁻²⁶ Kg *m/s2
or Fg = 1.64 × 10⁻²⁶N
Hence,
Gravitational force (Fg) = 1.64 × 10⁻²⁶N
Electrostatic Force (Fe) = 2.4 * 10⁻¹⁶ N

Mere hisab se option (c) correct hai bhai ek baar tu deekh le.
It's ok!
everyone have a 4 option to chosse or elese leave it. _/\_

10^-19 is charge, but gravitational force is charge independent. it depends only on mass and distance between masses only.
sorry bro
I made mistake u r right.
it's ok :)
