#UPSC asked about Forces of nature in #Prelims PYQ 2013

Forces of nature are divided in 4 classes👇

1. Gravity
2. Electromagnetism
3. Weak Nuclear Force
4. Strong Nuclear Force

If you are serious #UPSC aspirant, open this thread to learn about these forces🧵❤️ (1/5)

First, order of their strength:
Gravity < Weak Nuclear Force < Electromagnetism < Strong Nuclear Force

Second, take a look at the question asked in Prelims 2013.

Third (next tweet) the details of all 4 forces! (2/5)

1. Gravity

- Weakest of four
- Has infinite range
- Acts b/w object & mass
- Plays an 'attractive' force

2. Electromagnetism

- Has infinite range
- Can be attractive or repulsive force
- Weaker than Strong Nuclear Force
- Acts only on particles with electric charge (3/5)

- It has short range
- Responsible for radioactivity
- Considered to be a weak force

4. Strong Nuclear Forces

- Strong force with short range
- Holds protons & neutrons inside the nucleus of the atom (4/5)

Find all these forces in one place on my Blog to Revise later for #UPSC #prelims👇 (5/5)
