Hi Deepu,
The code is given below:

trigger tri on Account (after update) {
    
   tri_helper.acontPhon(trigger.new);
}

public class tri_helper {
    public static void acontPhon(list<Account> acList)
    {
       List<Contact> cList=new List<Contact>();
       
        for(Contact c:[SELECT Id,phone,account.phone From Contact Where AccountId IN:acList])
        {
            c.phone=c.Account.phone;
            cList.add(c);
            
        }
        if(cList.size()>0)

Hi Deepu,

I trust you are doing very well.

Below is the sample code which I have tested in my org and it is working fine. Kindly modify the code as per your requirement.
  
trigger CopyFromParentUpdate on Account (after insert, after update) {
    
    Set<id> setOfParentId = new Set<Id>();
    for(Account pt : trigger.new){
        setOfParentId.add(pt.id);
    }
    List<Contact> listChild = new List<Contact>([Select id, AccountId from Contact where AccountId in: setOfParentId]);
    List<Contact> updatedlistChild = new List<Contact>();
        for(Account pt : trigger.new){
            for(Contact ch : listChild){
                ch.Phone = pt.Phone;
                updatedlistChild.add(ch);
            }
        }
    if(updatedlistChild.size()>0){    
        Update updatedlistChild;
    }
}


I hope it helps you.

Kindly let me know if it helps you and close your query by marking it as solved so that it can help others in the future.
