If i do encapsulation, the vlans are able to ping each other which is not correct. I did trunking between the switches, trunking between switch and router. However it does not work, after i changed trunking to access, vlan 100 is able to ping other country network but for vlan 200 it is still unable to ping.

Wrong! This is correct and default behavior; You need ROAS or L3 switch with SVIs to route between VLANs.  VLANs do separate and split B-cast domains. That's their job. Traffic from vlan X is not reaching vlan Y by default;  L3 device is needed to route traffic between vlans;  " trunking between the switches, trunking between switch and router." is not enough.  Read CCNA chapter in https://www.ciscopress.com/articles/article.asp?p=2990405&seqNum=2

Note: by default and common practice is to have 1 subent per vlan. You have vlan 100 and vlan 200 in the same subnet 10.19.8.0 /22 (range 10.19.8.1 to 10.19.11.254) with all PCs in 2 vlans having the same gateway router and his IP (this is wrong).

You need another link to your Router or Router-on-a-stick (with sub-interfaces), aka ROAS, see chapter from the CCNA Odom's book is at
