Hi Kunal,
You can take reference from this below code. 
trigger CaseTrigger on Case (after insert) {
    if(trigger.isAfter && trigger.isInsert){
        Map<id,case> cas=new Map<id,case>([select accountid,projectid__c from case where id IN: trigger.new]);
        set<id> sid= new set<id>();
        for(case ca: cas.values()){
            if(ca.projectid__c!=null){
                sid.add(ca.projectid__c);
            }
        }
        map<id,project__c> proj=new Map<id,project__c>([select id,accountid__c,name from project__c where id IN: sid]);
        for(case ca: cas.values()){
            if(ca.projectid__c!=null){
                ca.AccountId = proj.get(ca.projectid__c).accountid__c;
            }
        }
        update cas.values();
